What If They Each Get 269 Electoral Votes?

Then it really gets interesting!

It becomes possible for us to have McCain selected as President by the House and Biden selected as V-P by the Senate. In the House, there would be only 50 votes, with each state's delegation getting only one vote, and, at 269-269, McCain would probably have won more states than Obama. In the Senate, each member gets to vote, and the Democrats will most likely control the Senate.
