Josh Shapiro I think is Dems' strongest candidate. His personality is very moderate even conservative but his policies are mostly liberal. PA is such an important state too.
I think Jon Ossoff could be interesting if he wins GA by a decent margin in 2026. He has an Obama-esque aspirational youth quality to him.
Ro Khanna's politics I think are well positioned for where the electorate is right now, not sure he's the ideal candidate, but he is good on the issues.
Gretchen Whitmer likewise is a popular governor in an important swing state
I feel like all of these feel like VP candidates though, no one feels like the alpha.
People who I think wouldn't be good:
Gavin Newsom - I don't think dude understands how much of a tool he comes off as. Leaning into Cali is not a winning strategy for Dems right now.
Pritzker - too fat and unlikable to win
AOC - too much of an internet personality, I think she would find outside of social media she's not that popular. The median voter is like a 50 year old cac from suburban Milwaukee.
I think either way JD Vance will be a tough candidate to beat. He is a more polished, smarter Trump. Dems bench is deep but not sure it's strong enough at the top.
