While too many republican politicians are not much better, for over the past 160 years, many democrats  are worse,  because democrats:

• (8) and many democrats engaged in massive voter fraud in the 2020 election in the USA, and other voter fraud over many decades:  source:  https://tinyurl.com/38zzcd6w
  

. . . and today, not much has changed, as many Democrats fuel racial tensions, hate, pit U.S. citizens against each other (regarding mask and vaccine mandates, CRT and indoctrination in public schools, defunding police, rioting, etc.), and pit U.S. citizens and illegal immigrants against each other, for more electoral votes based on the decennial census, which does not verify citizenship (notice the common-thread in all of the following):

• (01) ELECTORAL VOTES: because many Democrats despicably pit U.S. citizens and illegal immigrants against each other for more electoral votes, which are based on the decennial CENSUS, which does not verify U.S. citizenship, and does not contain a citizenship question (since Obama removed it in year 2010).  Also, the American Community Survey (ACS) forms (only sent to less than 3% of all 118 million households) are not the same as the CENSUS forms.    Therefore, districts and states with more illegal immigrants (who complete a CENSUS), will receive more representatives (in the U.S. House of Representatives), more electoral votes, more federal funding, and it helps to turn RED states to BLUE states.
• (02) DECENNIAL CENSUS:  because many Democrats are also fighting against a citizenship [x]check-box on the decennial CENSUS, despite the check-box being totally inadequate to prove citizenship.  Democrats disguise their desire for power (for THEIR party) as compassion for illegal immigrants, while despicably pitting U.S. citizens and illegal immigrants against each other for votes and money.
• (03) CRIME:  because many Democrats and most of the -MAIN STREAM MEDIA--> FAKE NEWS MEDIA  lie about crime by illegal immigrants, and refuse to report the 2,000 homicides per year by criminal non-citizens; and about 32% of everyone in federal prison is a criminal non-citizen. Also, many Democrats lie about crime rates by criminal non-citizens by trying to average crimes by criminal non-citizens for all 50 states, when 97.4% of all illegal immigrants are in only 10 states, and homicide rates are higher for criminal non-citizens than U.S. citizens in most of the states with the most illegal immigrants (i.e. CA, TX, FL, NY, IL, NJ, GA, NC, AZ, VA). 
• (04) COST:  because many Democrats, and most of the --MAIN STREAM MEDIA--> FAKE NEWS MEDIA, lie about how massive illegal (or legal) immigration is costing U.S. tax payers hundreds of billion$ per year ($296 Billion per year by this estimate) in net losses (which does not include all costs, and does not include the cost of crime by criminal non-citizens); that is a net loss of about $2,349.00 per year per household (126.22 Million households in 2017; U.S. population=323 Million in 2017); also see this daily ticker (at OANN.com) of the daily cost (about $0.75 Billion per day in 2019, now up to $1.1 Billion per day in 2021) due to rampant illegal immigration (excluding the cost of many crimes and about 2,000 homicides per year by criminal non-citizens );  for the 156 Million U.S. citizens employed in the U.S. in 2019, the cost to  each of them is  $1,763 due to illegal immigration ($275 Billion / 156 Million U.S. citizens employed in the U.S.); 
• (05) OPEN BORDERS: because many Democrats are calling for open borders, and refuse to adequately fund the building of more border barriers;
• (06) ABOLISH ICE: because many Democrats are calling to abolish I.C.E. (Immigration and Customs Enforcement);
• (07) ANOTHER SHAMNESTY: because many Democrats want another shamnesty, like the shamnesty of 1986;
• (08) eVERIFY:  because many Democrats refuse legislation to (a)require employers to use eVerify (to verify eligibility for employment); (b)to stop the abuse of asylum laws; and (c)stop the abuse of birth-right citizenship (women from all over the world are booking vacations to the U.S. to give birth, so that their child will have U.S. citizenship);
• (09) DRIVERS' LICENSES:  because many Democrats want to give illegal immigrants drivers’ licenses, and also automatically register them to vote; illegal voting by tens of thousands of non-citizens is widespread in all states;  and 81% of voter fraud convictions are by Democrats  based on Voter Fraud database [1979 to 2018];  and  60% of U.S. federal officials convicted of corruption are Democrats;
• (10) AIDING CRIMINALS: because many Democrats want more mayors like Libby Schaaf (Oakland, CA), who warns illegal immigrants (including criminal illegal immigrants) before an ICE raid to arrest criminal illegal immigrants;
• (11) SANCTUARY CITIES and STATES:  because many Democrats want more sanctuary cities and states, like California, where Democrats have passed sanctuary city and sanctuary state laws that protect criminal illegal immigrants (such as an illegal immigrant by the name of Garcia Zarate murdered Kate Steinle (who had already been deported 5 times, and convicted 3 times for felonies for manufacturing narcotics), and was then acquitted for that murder, despite Zarate admitting to shooting the weapon that killed Kate Steinle,  which should have been, at the very least, manslaughter);
• (12) 2nd AMENDMENT HYPOCRISY: because many Democrats want to abolish the 2nd amendment, but many Democrats and many on the left call for restricting or eliminating 2nd Amendment rights, and say it is worth it “even if it saves only ONE life”, but hypocritically ignore about 2,000 homicides per year by criminal non-citizens (source: https://www.gao.gov/assets/320/316959.pdf ;  https://site2data.com/homicides1.html ; https://site2data.com/cost2021.jpg );
• (13) ANYTHING FOR MORE VOTES: because many Democrats want (including Bernie Sanders, Kamala Harris, etc.) to pass new laws to allow criminals to vote (including murderers, rapists, child molesters, etc.), because they know that a vast majority of criminals will vote Democrat (because the Democrat party is essentially famous for pandering for votes, as they have also done by pandering to illegal immigrants). 
• (14) REPARATIONS:  because many Democrats are pandering for more votes by promising reparations for black people (including Kamala Harris, Bernie Sanders, etc.).  This is another example of Democrats using identity politics to acquire more votes.  Never mind that it would be punishing people that have harmed nobody.  It is yet another item in the long (and growing) list of things that Democrats will do for more votes and power.  In fact, many Americans' ancestors had nothing to do with slavery, because they immigrated to the U.S. after slavery was abolished.  Reparations are unconstitutional, since the 13th Amendment states "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States . . .".   Since no living Americans can be convicted of slavery, it would be unconstitutional to subject Americans to the economic "involuntary servitude" of paying reparations;  many democrats have also tried to push the narrative that the  U.S.A. is systemically racist, but the truth is, black people kill more than two times more white people, and black people make up 13% of the U.S. population (FBI source:  site2data.com/homicides_by_race.jpg).
  
• (15) FREE STUFF:  because many Democrats in many sanctuary states, allow illegal immigrants to pay in-state tuition, while U.S. citizens from other states must pay higher out-out-state tuition;  Democrat-controlled New York state legislature passed a law giving financial assistance for college to illegal immigrants in U.S. high-schools;  several sanctuary states passed legislation to allow illegal immigrants to attend tuition-free community colleges;  again, the Democrats will do anything for more votes, and power; many Democrats are incentivizing illegal immigration with promises of free stuff, including free stuff and welfare for illegal immigrants;
• NOTE:   Non-criminal illegal immigrants merely looking for work are not the true villains.  The truly despicable villains are many Democrats and similar ilk, who despicably pit U.S. citizens and illegal immigrants against each other for more votes, money, and power.

In addition to the above, more Democrats have been convicted of  corruption  and  voter fraud:

• U.S. federal officials convicted of corruption (60% are Democrats).
• and voter fraud convictions (81% are Democrats) based on Voter Fraud database [1979 to 2018].

Not to mention the following:

• Victims of Crime by Criminal Non-Citizens
• Victims Of Immigration Crime Engagement (VOICE)   
• Predator Illegal Aliens
• Immigrations' Human Cost
  
• Higher Homicide Rates by Criminal Non-Citizens than by U.S. Citizens
• Higher Homicide Rates for Illegal Immigrants in Arizona, California, and New York
• Non-Citizens Committed a Disproportionate Share of Federal Crimes from 2011-to-2016
• Non-Citizens Illegally Voting in U.S. Elections
