Will Romney file for the rest of his 2011 tax refund if he loses the election?

So Romney didn’t use several million in charitable contributions as deductions on his 2011 tax return because it would have brought his tax rate below 13 some odd percent. He has promised that he always paid more than 13% and this is what he had to do to make it true.

Of course, he can always file an amended return later, and claim the money he is legally entitled to. Then his tax rate will go below 12% or something. Lower than what he claimed, anyway.

So if he loses the election, do you think he will file an amended return? Why or why not? And if he does, will there be any political fallout?

For extra credit, if Romney loses, is his political career over?
