Nate from Tuesday:

Mr. Obama’s lead in the Electoral College is modest, but also quite consistent across the different methods. The states in which every site has Mr. Obama leading make up 271 electoral votes — one more than the president needs to clinch victory. The states in which everyone has Mr. Romney ahead represent 206 electoral votes. That leaves five states, and 61 electoral votes, unaccounted for — but Mr. Obama would not need them if he prevails in the states where he is leading in the polls.
