Will Harris be able to beat Trump should Biden not be able to go for a second term?
I'm not sanguine in a Harris victory in a Harris v. Trump election.
If Biden doesn't run, I fervently hope that the Democratic nominee is someone other than Harris.
Harris has been massively handicapped by the 50/50 senate of the last 2 years, she's had to be in DC pretty much every single day to be available to decide votes.
If the Democrats can win Georgia, she'll be free to do a lot more around the country, have more policy initiatives, build up her profile for election.
However I'd be looking at the Gergia governor election demographics and be very weary of a Harris presidential campaign. There are demographics in the USA who just will not vote for a black woman to be in power over them.
I also think one of the reasons Biden has done so well is (in the words of Fox News) "There's just not that much hate for Joe Biden out there like there was for Obama or Hillary". I think there's a lot of right wing hate towards Harris and maybe an outsider who hasn't had 8 years of solid demonisation from Fox and OANN will have a better chance at pulling centrist republicans and independents to the democrats.
