Washington (CNN) - President Obama and Vice President Biden are both returning to Ohio next week, the fourth White House visit to the politically crucial state in less than a month.
The White House said Thursday that President Obama will make remarks on the economy in Cleveland next Wednesday. Two days earlier, Vice President Biden will be in Toledo for Labor Day events.
Obama will bring the economic message to a state with an unemployment rate of 10.3 percent in July.
The trip will mark the president's 10th trip to Ohio since taking office. He joked during a June visit to Columbus that "(Gov. Ted) Strickland said I've been in Ohio so much he might start charging me for it."
But Strickland is a key reason Ohio is getting so much attention from the White House in the weeks ahead of the midterm election. The Democratic governor is in a close re-election battle with former Rep. John Kasich, the Republican nominee, and both Obama and Biden helped raise money for Strickland last month.
There is also a high profile Senate race for retiring Republican Sen. George Voinovich's seat, with Democrat Lt. Gov. Lee Fisher and former GOP Rep. Rob Portman competing.
And the state, a presidential bellwether that will be critical again to both sides in 2012, is also the site of three of the nation's most hotly contested fights for Democratically-held but vulnerable House seats.
President Obama was last in Ohio August 18th, holding a backyard town hall meeting and a Strickland fundraiser. Biden was in Toledo less than a week later visiting an auto plant and then raising more money for Strickland's campaign.
