(CNN) - Vice President Joe Biden's visit to Ohio Monday is the fifth to the state by either Biden or President Barack Obama over the past four weeks. But the flurry of trips by the top two men in the White House doesn't seem to be making a dent in a state where Democrats face challenging elections this year.
The vice president teams up with Democratic Gov. Ted Strickland at campaign events in Akron and Dayton. Next month the president joins Strickland on the campaign trail. The October 17 event will be the 11th time Obama has visited Ohio since he became president.
Biden's visit comes as the two most recent polls of likely Ohio voters indicate Strickland is slipping against former Rep. John Kasich, the Republican gubernatorial nominee. According to a CNN/Time/Opinion Research Corporation survey released Wednesday, Strickland trails Kasich by seven points. And a Quinnipiac University poll released Thursday indicates that Kasich holds a 17 point advantage over the first term governor.
In the race to succeed retiring Republican Sen. George Voinovich, Lt. Gov. Lee Fisher, the Democratic nominee, trails former Bush administration cabinet official and former Rep. Rob Portman by 11 points in the CNN/Time/Opinion Research Corporation poll. According to the Quinnipiac University survey, Portman holds a 20 point margin over Fisher.
And Republicans are confident they may be able to win back five to six Democrat held House seats in the state. Add that all together and it spells trouble for the Democrats in a state that's not only important this year but will also be crucial in the next race for the White House.
Ohio secured George W. Bush's re-election in 2004, but two years ago Obama won the state by five percent over Sen. John McCain in the presidential election. But according to the Quinnipiac poll, six out of ten Ohio voters disapprove of the job Obama's doing in the White House, with 38 percent saying they approve. The 60 percent disapproval is a new high for the president's disapproval rating in the Buckeye state.
The state's unemployment rate may have something to do with these numbers. Ohio's jobless level stands at 10.1 percent, above the national average.
"Ohio is the new Michigan. The state's economy is a mess, and Democrats are paying a steep political price for it," says Stuart Rothenberg, editor and publisher of the non-partisan Rothenberg Political Report.
Democrats made major gains in Ohio in 2006 and 2008. 2010 will not be a repeat performance.
"Another rosy speech from Vice President Biden won't change the fact that Ohio has lost over 130,000 jobs since the stimulus was enacted," Republican National Committee spokesman Ryan Tronovitch tells CNN.
