Good anylasis. But it may underestimate voter turnout for Romney. He does have a more difficult path, but if he sweeps all the swing states (even though not likely) he gets the magic 270 without Ohio. He most likely needs Florida, Ohio, Colorado, Nevada, & Virginia.
I have feeling Florida is gonna go Romney this year. Most of our independents are right of center and didn't like McCain. Romney moved to the center, but according to the polling data from that site, it's looking like it swung back to Obama. And his attack ads are ANNOYING AS ***!! *sigh* consequences of living in a swing state...
