DAVENPORT, Iowa — It’s the biggest bullhorn in the political world.

The presidency and all the attention it commands are giving Barack Obama a chance to frame the national story line this week, to try to put his imprint and spin on the economic and political wind shear that has been battering him.

His bus tour through three Midwestern states, complete with a blocks-long motorcade, is attracting the type of front-page headlines that a White House occupant can generate even with modest or rehashed proposals. A marvel of logistics, communications and transport that few organizations are equipped to execute, it’s a welcome advantage as he fights back in a noxious political environment and in the face of weakening public approval.

Wrapping up a forum on rural economies at Northeast Iowa Community College on Tuesday, Obama sounded a sentimental note about the appeal of the road.

“As I was driving down those little towns in my big bus, we slowed down and I’m standing in the front and I’m waving,” he said softly. “I’m seeing little kids with American flags, grandparents in their lawn chairs and folks outside a machine shop, and passing churches and cemeteries, corner stores and farms. I’m reminded about why I wanted to get into public service in the first place.”

He’s not the first and won’t be the last president to employ all the trappings of power to seek a connection with the public. Presidents get credit in the hinterlands just for showing up, even from those who don’t support them.

“I wish him well,” said Jim Pape, a 78-year-old retiree in Guttenberg, Iowa, who was having breakfast at a café when Obama and his entourage swooped in. “He isn’t all bad, but I’d prefer a different president.”

That’s praise from a man with this view of Washington: “They ought to plow it under and plant corn.”

The Des Moines Register, an influential paper in the region, ran two photographs and an article on the front page following Obama’s first day on the road. Nationally, the president also commanded prominent headlines and cable and network TV coverage. The president also expanded his Midwestern reach into Missouri by granting interviews Tuesday to television stations in Kansas City, Mo., and St. Louis.

Obama hit the road with slipping poll numbers, an up-and-down stock market, a downgrade of U.S. credit by Standard & Poor’s and the hangover of a bitterly fought debt ceiling deal. And he still managed to step all over the GOP presidential field, just as the Republicans were commanding attention with their Iowa straw poll, a big debate and the entry of Texas Gov. Rick Perry into the race.

Obama’s tour put all the trappings of power on full display. He boarded his Marine One helicopter on the White House lawn to fly to nearby Joint Base Andrews in Maryland. From there he flew on Air Force One to Minneapolis-St. Paul, Minn. There he boarded his new $1.1 million Secret Service armored bus, joined a motorcade of up to 30 vehicles and rambled about 375 miles through Minnesota and Iowa corn fields and small towns. The trip was to end Wednesday.
