The latest and last prediction before the election from a state-level economic model by The University of Colorado, here, shows Romney winning in November with 330 electoral college votes to Obama's 208:
The model foresees Romney carrying New Mexico, North Carolina, Virginia, Iowa, New Hampshire, Colorado, Wisconsin, Minnesota, Pennsylvania, Ohio and Florida. Obama is predicted to win Michigan and Nevada.
Rasmussen differs in that he has Obama strongly carrying New Mexico, Minnesota, and Pennsylvania, as of tonight, and Romney strongly polling in none of the states he's supposed to carry according to the Colorado model.
Rasmussen also shows Obama narrowly polling ahead in Wisconsin, Ohio and Nevada.
Assuming those 6 states go for Obama, along with Michigan, that would put North Carolina, Virginia, Iowa, New Hampshire, Colorado, and Florida in Romney's column (narrowly), totaling 267 electoral college votes, just shy of the needed 270 if the rest of Rasmussen's map is correct.
Obama taking Wisconsin and Ohio and Nevada would give Obama 271 to win if the rest of Rasmussen's map is correct.
That result would mirror the year 2000 contest between George W. Bush and Al Gore, only flipped this time favoring the incumbent Democrat Obama.
