CHEYENNE -- Iowa's governor plans to visit Wyoming this weekend to stump for Barack Obama, while a former Wyoming governor is throwing his weight behind Hillary Clinton.

Current Wyoming Gov. Dave Freudenthal, meanwhile, remains publicly uncommitted -- even as the Obama-Clinton race remains close and the state's Democratic caucuses draw near.

Iowa Gov. Chet Culver plans to visit the state Obama headquarters in Cheyenne around noon on Saturday before going to Laramie to rally Obama supporters, said Gabe Cohen, state director for the Obama campaign.

Cohen said Culver will then return to Cheyenne to speak at the state Democratic Party's annual Nellie Tayloe Ross Banquet on Saturday night.

"He's been out in other states doing similar trips," Cohen said Thursday. "As a governor of Iowa, he was able to see each and every candidate pretty up close and personal, so he's got some good insight into Senator Obama."

Clinton's campaign on Thursday announced that it had formed a state steering committee that includes several well-known Wyoming Democrats. Most prominent is Mike Sullivan, Wyoming governor from 1987 to 1995 and U.S. ambassador to Ireland from 1999 to 2001.

"Hillary is committed to solving the problems facing so many in Wyoming, from a health care plan that covers everyone to a plan creating greater opportunity in rural America," Sullivan said in a release from the Clinton campaign.

"I know Hillary to be someone who seeks solutions that create change, and we will be working hard to spread her message here in Wyoming."

The steering committee also includes former Wyoming Secretary of State Kathy Karpan and state Sen. Rae Lynn Job, D-Rock Springs.

Freudenthal said at his regular news conference Thursday that Culver had told him about his plans to visit Wyoming. But Freudenthal repeated his stance that he had no plans -- yet -- to back Obama, Clinton or any other candidate.

"He called me and said, 'Now I want to see you while I'm out there,"' Freudenthal said of Culver. "And I said, 'Well, you'll see me.' And I will. I'll spend some time with him. And obviously there are some prominent Wyoming people who are supporting Clinton, and I certainly do like all of my friends."

Seven national Democratic delegates, out of 18 total from Wyoming, will be directly at stake in the state's March 8 county conventions.
