No, they clearly do not "know" Joe Biden at all. If people actually knew his record of racism, cutting government programs, and sexual harassment allegations and not JUST that he was the guy attached to Obama, they'd be regretting each and every one of their primary votes. Instead, the Democratic party has proven they more under-informed than ever, and the party will probably die after Biden fails to secure the rust belt states in November and go on to fail the presidential election. Oh yeah... we seem to forget about the few states that actually determine the presidential election. Good luck telling them they should vote for the guy who supported NAFTA. That worked out great in 2016.
