* Obama hits Iowa, Minnesota, Illinois in 3-day bus tour
* Trip tests campaign organization, grassroots support

WASHINGTON, Aug 15 (Reuters) - President Barack Obama heads out on Monday on a bus tour of Minnesota, Iowa and Illinois in the U.S. Midwest, aiming to leave behind doubts about his leadership that could dent his 2012 re-election prospects.
The three-day trip takes him to three states vital to retaining the White House in the November 2012 election, but could expose Obama to voters who, polls suggest, are furious about political gridlock back in Washington. Obama won all three states in the 2008 presidential election.
The White House says Obama is on listening tour to hear from Americans about the economy and to talk about how to boost jobs and hiring. There are no plans announced for a major policy speech to roll out new initiatives for economic growth.
Obama is due to speak at a town hall style meeting in Cannon Falls, Minnesota on Monday before heading to Decorah, Iowa. He then holds a rural economic forum in Peosta, Iowa, on Tuesday and holds town hall meetings in Atkinson and Alpha, Illinois on Wednesday before returning to Washington.
The unmistakable campaign style of the trip will help the Democratic president test his organization and grassroots support as the field of Republican presidential candidates takes clearer shape.

Iowa, which launched Obama’s historic journey to the White House in 2008, has recently been playing host to Republican presidential hopefuls who have been criticizing his record as they crisscross the state.

Obama’s departure follows a spate of bad news that has dented confidence in his leadership, particularly after weeks of bitter debate to raise the U.S. debt limit that left exposed deep partisanship verging on government dysfunction.
