The Obama-Biden campaign is sending seven-time Grammy winner will.i.am and actress-producer Vivica A. Fox to Cincinnati Saturday for a "Party at the Polls" event outside the Hamilton County Board of Elections.

"Party at the Polls" begins at 10 a.m. outside the board of elections at 824 Broadway downtown.

The board offices will be open from 8 a.m. to 2 p.m. Saturday for early voters, as well as from 1 p.m. to 5 p.m. on Sunday and 8 a.m. until 2 p.m. on Monday.

Four years ago, then-senator Barack Obama held a rally at the University of Cincinnati on the Sunday before the election, his final stop in Cincinnati before going on to win Ohio and the White House two days later.

This year, Obama - now locked in a tight re-election campaign where Ohio will play a crucial role - will return to the same Sunday for a rally at UC's Fifth Third Arena in what is likely to be his final campaign appearance in the area before Tuesday's election.

President Obama - who had originally planned to be in Cincinnati Wednesday - will hold a campaign event here Sunday as part of a weekend push through key battleground states.

And First Lady Michelle Obama is planning on a rally Saturday afternoon on the campus of Miami University in Oxford, the alma mater of GOP running mate Paul Ryan.

President Obama holds a two percentage point lead over Republican Mitt Romney in the Ohio Poll released Wednesday afternoon by the University of Cincinnati's Institute for Policy Research.

That is well within the poll's margin of error of plus or minus 2.9 percent, meaning the race in Ohio is extremely close and the end result is a toss-up.

The poll had Obama with 48 percent support to 46 percent for Romney.
