The Democrat party had a favorable rating in the damn TEENS, so they already were mired in toxic corruption and stone-deafness. What do you gain by propping up a tired corrupt old horse?
Where are you getting that number from?
HuffingtonPosts's charts have them at around 40% approval (50% disapproval). It was higher last year during the election though. (I won't even bother about asking about the rest of your assertions in that post). Sometimes people advertise the difference between those two, which is -10 I guess (Sanders is +22, which is insane).
I was geniunely surprised to see people so mad at the Democratic party all the sudden in 2016. Like, I thought everyone was on board. We're moving forward on healthcare. Finally actually taking on systemic racism. Fighting against big money. Helping kids pay for college. Still bombing people, which sucks, but we can't have everything. Suddenly the election rolls around and everyone starts screaming "You're corrupt! You love big money. You hate black people." I think the entire party was kinda shocked. I was at least. I guess we're deaf or something, but I never really heard anyone telling Obama he was corrupt, racist scumm, and the platform really hadn't changed... at all from his.
I agree that we're doomed at this point. I have no hope left for the Democratic party. They're doomed. The GOP could run a bag of dicks and shit in 2020 and still win.
