DNC platform is tax the rich, raise minimum wage, and fund social programs. They have had 48 or less senators for over 13 years, currently 45. The last time they had 58 for less than two months they caucused with 2 independents to pass Medicaid. They would have launched a Public Option identical to Germany's healthcare if not for one of those independents opposing it.
DNC is liberal, DNC is on our side, Vote DNC. Or, if an independent polls higher, then vote for them because at least they're not a Republican and removing every single Republican should be our goal.
