Obama leads by 2 percentage points in Wisconsin, according to the Real Clear Politics average of polls.

The latest Marquette poll was conducted before Tuesday night’s town-hall debate, but shows how much Romney gained on the president on the strength of his overwhelming debate victory earlier this month in Denver.

Marquette University polling director Charles Franklin said over Twitter that the race in Wisconsin is “as close as it could possibly be.”

Obama’s lead among women in Wisconsin was 25 percentage points in the previous poll, and Romney has since cut that lead to 4.

Romney’s favorability rating also got a significant boost, from 39 positive and 53 negative in mid-September to 43 positive and 48 negative presently.

Obama’s favorability rating is still above water, at 52 positive and 44 negative, but down from his 56-41 score in the previous poll.
