There should be bit more thorough and precise reports on this but for now:

An average of polls by RealClearPolitics.com in several swing states also showed a tightening in the race in some of the places where the election will be decided. Romney was about even with Obama in Florida and Virginia and 3 points behind him in Ohio.

A poll by Public Policy Polling, a Democratic organization, had Obama up by only 2 points in traditionally Democratic Wisconsin. Previous polls had shown a comfortable lead for the president.

Not taken into account yet was the possible impact of the improvement in the U.S. jobless rate announced on Friday. It fell to 7.8 percent in September, the lowest in almost four years, and gave Obama a talking point to defend his stewardship of the economy.
