President Obama also now leads in Ohio by 9 points. Poll: Sherrod Brown surges in Ohio

As President Barack Obama has gained in Ohio polls, so has incumbent Democratic Sen. Sherrod Brown, who has now jumped out to a 10-point leadover GOP Senate candidate Josh Mandel, according to a poll released Monday.

A survey from the Columbus Dispatch found Brown ahead of Mandel by a margin of 10 points, 49 percent to 39 percent. The last Dispatch poll, out Aug. 26, had the two candidates tied at 44 percent.


Obama, who now leads Republican presidential candidate Mitt Romney in Ohio by 9 points — 51 percent to 42 percent — according to a Dispatch poll, was also tied with the GOP standard-bearer in a previous Dispatch survey from late August.

“Both changes were fueled by a larger proportion of Democrats in the current poll who say they will vote,” the newspaper reported.

Mandel, the state treasurer, is trailing Brown among most key demographics and voting blocs, including independent voters, the survey found, but the Dispatch also noted that factors like three upcoming Senate debates could still affect the outcome in the Buckeye State.

The poll of 1,662 randomly selected likely voters in the state was conducted via mail from Sept. 19 through Sept. 29 and has a margin of error of plus-or-minus 2.2 points, the survey said.
