LIMA, Ohio (CNN) - It all came down to Ohio in the last presidential election, and a new average of the latest polls in this crucial battleground state indicates that the state is once again up for grabs.
George W. Bush's narrow victory in Ohio four years ago put the President over the top in his bid for re-election. This time around, Ohio could be just as crucial to the outcome of the race for the White House.
A CNN poll of polls compiled Saturday afternoon suggests that Barack Obama has a five-point lead in Ohio, 49 percent to 44 percent, with 7 percent of voters undecided in their choice for president.
This new edition of CNN's Ohio poll of polls consists of five surveys, an Ohio Newspaper poll conducted October 18-22, a Quinnipiac survey taken October 16-21, a CNN/Time/Opinion Research Corporation poll conducted October 19-21, a Suffolk University survey taken October 16-19, and an NBC/Mason Dixon poll conducted October 16-17.
Senator Barack Obama, D-Illinois, was up by 7 points over Senator John McCain, R-Arizona, in the previous CNN Ohio poll of olls, which was compiled on October 23.
Both candidates, their running mates, and their surrogates, are spending a lot of time campaigning in Ohio. And Ohio voters are getting inundated with campaign television commercials. The McCain and Obama campaigns have spent a combined estimated $29 million in advertising in Ohio this election cycle.
