He also pointed out how the Dems have a history of running a VP candidate who is a fierce rival of the Presidential candidate. Lyndon Johnson was one. Heck, when the country was new, the person who came in second in the Prez race became the VP. That was changed in 1804 with the 12th Amendment.
To add to the amusements, the electoral college can vote any way they please. Each elector has two votes, one for Prez and one for Veep. It's not against the rules for them to cross those up - this actually happened during the 1988 election - one elector cast his Prez vote for the Demo Veep candidate.
Bottom line - let the process play out.
