Poll: Obama leads Republicans in Wisconsin

MILWAUKEE (AP) - A new poll shows President Barack Obama easily leading each of his four Republican rivals in Wisconsin.

A Marquette University poll released Wednesday shows Obama leading former Sen. Rick Santorum, 51 percent to 40 percent, and leading former Gov. Mitt Romney, 53 percent to 38 percent.

The poll questioned 716 registered Wisconsin voters from Thursday to Sunday. The overall margin of error is plus or minus 3.7 percentage points.

Against Rep. Ron Paul, the poll shows Obama leading 52 percent to 36 percent, and the president holds a lead over former House Speaker Newt Gingrich, 56 percent to 33 percent.
