CHEYENNE -- Democratic presidential candidate Hillary Rodham Clinton plans to open campaign offices in Casper and Cheyenne sometime during the next week.

Clinton spokesman Blake Zeff said Friday the campaign has also sent at least four paid staffers to Wyoming to drum up support.

Zeff said the campaign has found considerable support in the state.

"We're thrilled by the outpouring of grassroots support for Sen. Clinton in Wyoming. We're going to be working hard to harness that enthusiasm and bring out support for her," he said.

Clinton is locked in a tight race for delegates with Illinois Sen. Barack Obama, who last week opened offices in Casper, Cheyenne, Laramie and Rock Springs.

Both campaigns are focusing unprecedented -- at least in modern memory -- attention on a state that will have just seven delegates directly at stake in caucuses March 8.

Not to be outdone, Obama's campaign said it has mobilized 2,000 volunteers -- out of roughly 30,000 registered Democrats statewide -- and sent a dozen paid staff to the state.

"We've got a lot of work to do," Obama campaign spokesman Matt Chandler said.

Obama had a nearly 100-delegate lead over Clinton on Friday. Clinton has been banking on reducing if not eliminating that lead with the big Texas and Ohio primary events on March 4. She has led Obama in polling in both states.

Four days after that come Wyoming's Democratic county conventions.

Wyoming has 18 Democratic delegates. In addition to the seven chosen March 8, the party will choose three at-large delegates and two state party leaders or elected officials as delegates at its state convention in May.

The state party also has five Democratic superdelegates who automatically will get to go as delegates. They include Gov. Dave Freudenthal and state party Chairman John Millin. The final delegate is appointed by Millin.
