A 269 -269 tie goes to the house with each state getting one vote - we lose under this scenario given the current congressional breakdown.
Fox just called Ohio so I’ll see you when Tim Kaine’s seat is open
A tie doesn’t =a McCain loss since there would be more McCain states than Obama states. The delegations would have to decide to they vote with their party or with the wishes of the voters. If more delegations decide to go with the wishes of the voters McCain would win.
