Why does the Democratic Party continue to pick presidential candidates who embody everything the left hates?

Why do guys keep doing this? Joe Biden is directly responsible for SO MUCH **** that the left despises. His fingerprints are on virtually every piece of horrible legislation going back like 30 years.

-The horrendous 1994 crime bill which introduced mass incarceration to millions of black Americans 

-The Omnibus Counterterrorism Act of 1995 which went on to become---you guessed it---the Patriot Act, which Joe ALSO voted for in 2001

-Repeal of the Glass Steagal Act which as you know was one of the primary catalysts in the Housing Bubble collapse of 2007-2008

-Resoundingly supported and voted for the Iraq War in 2002, which as we all know was just a brilliant idea

And let's not even get started on how goddamn creepy the guy is with literally every female in his vicinity, or his spectacularly racist views of black Americans in particular.

You have nominated Ronald ******* Reagan with a "D" by his name. Do you realize this?
