They'll run their media machine of slander on whoever happens to run. In a sense it's largely up to the media how effective that is. I saw a recent polling graph on here showing the composition of the dem base. The progressive flank is lager than the liberal and moderate one combined now.
AOC is not a monolith, nor is she beyond corruption, but I think she has the education, youth and talent to lead a generation back into politics. I'm unsure how being a bartender in the Bronx to fund your house keeper mother is privilege or living with three other people in DC and shopping for bargain shoes, but perhaps I'm missing something there. Also, I think she has tons of risk. Specifically being primaried from within her own party or from people out to stalk her (which has happened) but OK.
Who would you like to see run for president that's better?
Edited: said the same thing twice about polling, so deleted an instance.
