So I was listening to this Chris Bouzy guy
He says in one of those pods (first link) that if Biden is NOT at the top of the ticket, Trump has a 65% chance of winning, will probably get 327 electoral college votes and the GOP will win finish 52 seats in the Senate. House tilts GOP.
And then he says if Dems become united and stay with Biden at top of the ticket
The Dems would win 350 electoral college votes, hold the Senate and get 30 seats in the House to win the majority.
