AQuinnipiac University poll released this morningshowed President Obama with a five percentage point lead over Mitt Romney in Ohio - unchanged from the polling institute's last Ohio poll on Oct. 22.
The same poll looked at two other key battleground states - Florida and Virginia - and concluded that they were too close to call.
In the poll, Obama had 50 percent to Romney's 45 percent in Ohio.
In Ohio's U.S. Senate race, Democratic incumbent Sherrod Brown led Republican challenger Josh Mandel by nine percentage points - 51 to 42 percent.
In Florida, Obama had 48 percent support to 47 percent for Romney - considerably down from the nine percentage point lead Obama enjoyed in the Sept. 26 Quinnipiac Poll.
In Virginia, Obama was at 49 percent support compared to 47 percent for Romney, compared to the five percentage point lead Obama had in Virginia on Oct 11.
By wide margins, voters in each of the three states say that Obama cares about their needs and problems more than Romney, but Romney had the advantage when asked who was seen as a leader.
Quinnipiac surveyed 1,110 likely Ohio voters from Oct. 23 through Oct. 28. The margin of error in the poll is plus or minus 2.9 percent.
