Caucus sites are moving from living rooms to meeting halls because the neck-and-neck nomination fight between U.S. Sens. Barack Obama, D-Ill., and Hillary Clinton, D-N.Y., is still very much alive and Wyoming, for now, is a Democratic battleground and far from irrelevant.

Former U.S. President Bill Clinton and daughter Chelsea have been criss-crossing Wyoming with "Solutions for America" events on behalf of Hillary Clinton, who broke a string of losses on Tuesday by winning in Ohio, Rhode Island and Texas.

She had several Wyoming stops planned Friday, including a town hall meeting in Cheynne, the Wyoming Tribune-Eagle said.

Obama also was touring Wyoming with a "Stand up for Change" town hall meeting scheduled for Casper and a rally in Laramie.

The state party has 18 national delegates to apportion. Twelve of these will be decided by Saturday's the caucus votes. Six others, including five super delegates, could go to the August convention in Denver uncommitted.
