(CNN) – A new poll released Sunday indicates Democratic Sen. Sherrod Brown of Ohio has a seven-point advantage over Republican opponent Josh Mandel.
Fifty-two percent of likely voters in the Buckeye State back Brown, while 45% support Mandel, according to the Ohio Newspaper Organization Poll conducted by the University of Cincinnati's Institute for Policy Research.

Brown expanded his margin over Mandel since the institute conducted a survey last month, when Brown was ahead of his opponent by only one percentage point.
However, two other polls in the last two weeks have also indicated Brown carries a seven point advantage over Mandel.
Brown, elected in 2006, maintains his edge despite a flood of spending from outside conservative groups, including Crossroads GPS and the U.S. Chamber of Commerce.
Earlier this month, Crossroads released a new ad targeting Brown for supporting President Barack Obama's health care reform. The football-themed ad says Ohio has lost more than 280,000 jobs "under (Brown's) leadership" and attacks the senator for supporting President Barack Obama's health care reform.
"Ohio just can't compete as long as Sherrod Brown is calling the plays," the ad's narrator says.
Mandel, the state treasurer, hasn't fallen too far behind in fund-raising, however. The Republican has raised $9.9 million this cycle compared to the Democratic incumbent's $11.1 million, according to filings with the Federal Election Commission.
Despite Brown's seven point lead, the contest will likely remain tight in the final 43 days of the campaign.
"The Brown-Mandel race may turn out to be one of the harder races to handicap this fall," said Eric Rademacher, co-director of the Institute for Policy Research, told the Columbus Dispatch.
Political analysts Charles Cook and Stuart Rothenberg rate the race as "leaning Democrat," or in between a "toss up" and "tilting Democrat," respectively.
The University of Cincinnati's Institute for Policy Research questioned 861 likely Ohio voters by telephone between September 13 and September 17. The sampling error is plus or minus 3.3 percentage points.
Absolutely NAIL him on Obamacare and state the ONLY way to repeal it is to get Democrat Obama droids like this OUT of the Senate.
Sen. Brown has this election in the bag despite how much special interest money Karl Rove throws into the race. The problem that Rove and his foreign donors don't understand is that Sen. Brown is really for the middle class. He's introduced legislation AGAINST China and our trade policies with them. So those ads from the Robmey campaign and Crossroads misrepresenting the truth about the President allowing China to cheat is just a bunch of BS.
You go Senator Brown!!! Ohio voters seem to be getting the message " Gop is "Rolling Calamity" Save America, Vote Democratic across the board!! Obama-Biden 2012
Yahoo! Vote the Repub Tea Party out!
Good for your Sen. Brown – you are a rare voice of reason in a Senate that has become paralyzed by obstructionist tactics and partisan hacks. And it should be noted that Romney is poisoning dozening of down-ballot races. A word of thanks to our GOP friiends for that one.
how are 28,000 Ohio jobs lost under Sherrod's leadership when Kaisch is Governor. Get Kasich out of their and then we can talk...
@truth hurts – Absolutely NAIL him on Obamacare and state the ONLY way to repeal it is to get Democrat Obama droids like this OUT of the Senate.
I love how all the right wing Faux Noise parrots are so-o-o-o keen to repeal their OWN freakin' healthcare plan. Hypocrisy rules the day.. Obmacare as you love to hate it, is actually 95% a REPUBLICAN health plan (based on MA), INCLUDING the individual mandate which the GOP wanted in Clinton's plan. They then spend MILLIONS in tax payer dollars taking their own plan all the way to the SCOTUS to get it repealed – all because the Obama administration passed it. What a bunch of cry-babies.
Brown needs to wipe the carpet here !
How can republican governor John Kasich say that jobs are returning to Ohio and republican candidate Josh Mandel say the opposite?
Only in republican world can two people from the same side have diametrically opposing opinions.
Keep up the good work Mr. Brown, maybe with your help and more help of democrats like you we can rid the house and senate of obstructionist republicans.
You gotta lust love how Democrats won't even accept responsibility for Obamacare, their "signature achievement" in four years, after they forced it through without a single Republican vote using lies and bribes. Oh wait, 60% of the American people want it repealed. That might help explain it.
Wait a minute ... aren't these the same jobs that Kasich got elected on blaming them on Ted Strickland?
Mandel (Brown's opponent) has said that he will "change Washington" ... does that mean he WILL vote for some of the thing that Pres. Obama puts forth? Or is he going to "change" DC by doing exactly what the Teahadists tell him to do, which is what's going on right now???
Or is he, like the treasurer's office, going to file for candidacy for President as his first act as a Senator? Mandel PROMISED he was going to spend his term as Treasurer and not seek the Senate ... PROMISE BROKEN barely after the paint was on his office door.
People tend to forget (another anti-Sherrod Brown ad) that gas prices rose 30 cents a gallon in the two weeks after the Republicans re-took the House and Kasich took the Governorship, and until then, the price of gas was just barely above $2 a gallon.
And "Jobs"? (Well, they're not # 1 priority to Repugs) Kasich refused the high-speed rail system, but demanded the money set aside for it.
