- if he ran as VP for another person, which is constitutionally allowed, he could be elected as VP
This is an interesting, but untested, legal theory. When Al Gore ran in 2000, there were murmurings of whether he should try to get Bill Clinton on the ticket as VP. Ultimately, there was some consensus that this part of 12th Amendment wasn’t superseded by any others: “But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States.”
It’s a bit of an open question whether that means only those parts of the eligibility requirements in place at the time (35 years old, natural born citizen, etc), or whether new requirements are also included, such as already serving two full terms as President. Clinton/Gore didn’t want to push those boundaries, but Trump certainly could try.
Edit: The 2012 book Constitutional Cliffhangers has a whole chapter dedicated to this and similar scenarios. It became a must-read in Trump’s first term, and is even more of one now.
Left of global center? No. Left of USA center? Probably.

More Americans identify as conservative than liberal. It’s not something we have to like, and certain policies may be quite different individually, but in order to win nationally, Democrats have to defeat voters’ own self-identification. Obviously it happens, so this isn’t some insurmountable challenge, but the deck is stacked.
