Mitt Romney Casts His Vote ... for Mitt Romney

It's ON!!! The election is officially underway ... and Republican candidate Mitt Romney has officially cast his vote for President of the United States ... probably for himself.

Mitt -- along with his wife Ann -- hit up their local polling place in Belmont, Massachusetts this morning ... with some big, confident smiles.

According to every media outlet in America, the race is super close ... and will come down to the wire.

So, you can either drive yourself crazy watching all of the election coverage ... oooooor there's a brand new "Sons of Anarchy" on F/X tonight.
