Irrelevant. The electoral college delegates are bound and cannot change their votes. There is also only one round of voting in the electoral college.
Try again.
There are some state laws that say such, but this has never been tested. Say the "president" chosen in November rapes and murders a nun before the election in December. You telling me that the electors chosen can't vote for anyone else?
Nonsense. Electors are entirely free to vote as they see fit.
