The US President, Mr Barack Obama, will go on a bus tour across three states in Midwest, which his aid say is part of his effort to spread the message of economy, while political analysts termed it his pre-election campaign to connect directly with the people.

“The President will discuss ways to grow the economy, strengthen the middle class and accelerate hiring in communities and towns across the nation and hear directly from Americans, including local families and small business owners,” the White House said in an announcement.

Mr Obama would be travelling to Midwest on a three-day economic bus tour, from August 15 to 17, making stops in southern Minnesota, northeastern Iowa and western Illinois.

He had carried through all these three states in the 2008 presidential elections.

“The President knows we must do everything we can to promote economic growth, restore confidence in our nation’s future and restore the sense of optimism for future generations,” the White House said.

“The President looks very much forward to getting out in the country — he’s obviously spent a lot of time here in Washington and in the White House of late — and to hearing from Americans, in the Midwest... about what’s going on in their local economies, what they think Washington can and should do to enhance economic growth, enhance job creation in their parts of the country,” White House press secretary, Mr Jay Carney, said.

“And that’s what this trip will be about,” he said, adding that Obama’s message would be clear economy and job.

His effort to connect directly with the people comes at a time when his popularity rating has hit an all-time low — 40 per cent according to the Gallup poll — and the Standards and Poor’s unprecedented decision to downgrade America’s credit rating from AAA to AA+.
