A new poll released Wednesday shows President Obama and Mitt Romney tied in Wisconsin, erasing the significant lead that Obama had built following the Democratic convention and putting the state's 10 electoral votes firmly in play.
The Marquette Law School poll shows Obama leading Romney, 49 percent to 48 percent, well within the poll's margin of error of plus-or-minus 3.4 percentage points. Only 2 percent of voters remain undecided.
In late September, just before Romney's impressive performance in the first presidential debate, Obama held an 11-point lead, 53 percent to 42 percent.
Likely voters are split on the president's job performance: 48 percent approve, and 48 percent disapprove. A slim majority, 52 percent, view Obama favorably, compared to 45 percent who view him unfavorably. That is slightly better than Romney's image, which is 46 percent favorable, versus 48 percent unfavorable. Forty-nine percent of Badger State voters have a favorable impression of home-state Rep. Paul Ryan, the GOP vice-presidential nominee.
The poll of 870 likely voters was conducted Oct. 11-14, largely after the Oct. 11 vice presidential debate featuring Wisconsin Rep. Paul Ryan.
