The results of Nate Silver's 538 model, Real Clear Politics' average tracker, and Sam Wang's model are starting to converge. As of 6 am ET on November 1st, the numbers are:
538: Obama 300 EV, Romney 238 EV (I rounded down for O, up for R)
RCP: Obama 290 EV, Romney 248 EV (the "No Tossup States" line)
PEC: Obama 303 EV, Romney 235 EV
Could it still swing to Romney? Yes, it could but increasingly looking very unlikely. If Romney were to win it would be akin to a "Dewey Defeats Truman" moment.
I'd much rather be in Obama's position than Romney's five days before the election.
