Uh, guys the President of the Senate is Dick Cheney, the Vice President. Byrd may have been President Pro Temp.
And, of course, this office petitioned has no authority in such a matter.
Well, the electoral college has to vote — I can’t imagine 79 or whatever faithless electors (even at the revelation that Obama is not a native), but if that hurdle is crossed, then if objections are raised by one Senator and one Representative (the counting is presided over by the VP), each house shall consider the matter.
See 3 U.S.C. 15.
If the two houses come to opposite opinions then the governor certifies which votes are counted — although I don’t anticipate any state sending shadow electoral votes.
Now if both houses agree to throw out Obama votes (unlikely) then Amendment 12 is invoked. Here the choice is limited to three options. McCain would be one, then the next two on the list receiving electoral votes, if there are any.
At this point I would expect the House to elect Obama even if unqualified. Then Biden would become President under Amendment 20.
