The Mitt Romney campaign will be heading to Iowa next week but, much to the frustration of Republican leaders in the state, it’s anyone’s guess as to where it may go.

Several County GOP leaders across Iowa today told ABC News that they’re “disappointed” that they haven’t heard anything from the Romney campaign ahead of next week’s visit.

Former Massachusetts Gov. Romney hasn’t visited the Hawkeye State since August and his campaign will only confirm a trip to “western Iowa” at the end of next week.

Sioux County Republican Chairman Mark Lundberg said his county – one of, if not the most, conservative counties in the state - is seeing candidates “a lot less this time than in years past.”

“I just hate that as an advocate for the party, we get no heads up,” said Lundberg of the mysterious visits by the GOP contenders. “This is the ground zero for conservative politics.

“They just call us [at the last minute] and say, ‘OK, we’re going to be here,’” he said.

Lundberg is often asked, he said, to help populate the campaign stops for candidates.

“It’s very frustrating,” he said. “Nobody plans ahead. They just show up and our objective is [that] if a candidate comes through my county I want my people to be given a chance to listen to them.”

Lundberg said it’s not just the Romney campaign that has been managing its Iowa affairs “from afar,” but also Texas Gov. Rick Perry’s. Perry’s campaign reached out to Lundberg just 48 hours in advance of his stops in the county last week, he said.

Jeff Jorgensen, the GOP chairman in Pottawattamie County, also in the western part of the state, agreed with Lundberg, adding that he’s had “no heads up” about a Romney visit next week.

“We are somewhat disappointed we haven’t heard much,” he said.

The location of one of Romney’s Midwest stops has leaked – and it will be just over the Iowa border in South Dakota. Romney will be the keynote speaker for the Sioux Falls Area Chamber of Commerce’s annual meeting on Oct. 19.
