Obama's Lead by State

This shows Obama's lead over Romney as of November 2 (states where Romney leads are shown as negative). The states are ranked from Obama's greatest lead on the left to Romney's greatest lead on the right. For most states I used the most recent available poll results. If more than one poll was done at about the same time, I used the results of the one with the smaller margin of error. For the few states where no poll has been conducted, I used the results of the 2008 presidential election. This places the electoral vote count at 272 to 251, with Obama in the lead (I didn't count North Carolina on either side since the polls say there is an equal split there). To pull off a victory, it now appears Romney would have to win over North Carolina and Iowa. I'll try to make some improvements for future versions on this chart.
