Early exit polls: Romney leading? Update: Mitt 35, McCain 29? Update: McCain leaves Michigan

We all know the lessons of 2004 so discount accordingly, but a site called Huliq says an AP poll shows Mitt out in front. Credible? Judging by the AP’s partisan breakdown, yeah: Democratic/independent turnout is lower than it was eight years ago when McCain won, boding ill for Maverick and well for a Romney comeback.

Polls close at 8 p.m. ET. Hold your breath.

Update: A six-point win? Sweet if true.

Update: InTrade’s reporting a 30-point swing today in Romney’s favor. Someone knows something.

Update: The writing’s on the wall.
