But what I wouldn't GIVE to see Mike Pence, at 11:59 am break the tie securing Donald Trump the election

Pence could only break a tie for VICE PRESIDENT (electing himself).

The Senate has nothing to do with electing the President.

I think that, in the given (unlikely) scenario, it would come down to Pence. Asshole Democrats would push it to the limit.
