Why not? Neither the Electoral College nor electoral votes would be involved.
Indeed. I was thinking of something else. My booboo.
Interestingly, however, there is the usual practice of the major parties to run Pres and VP candidates from different states. This is for at least 2 reasons, both practical not constitutionally-mandated. First, it might attract more votes. Second, the Constitution (12 Amendment) does require each state’s electors to vote for at least one of the two from a state not their own.
Thanks!
