ORLANDO (CBSMiami/NSF) – Former House Majority Leader Adam Hasner scored a victory in a U.S. Senate straw poll by conservative activists Friday, a win that could raise the stature of his campaign and emphasizes the problems one of his major primary rivals faces with Republican base.

Hasner carried 34 percent of the 1,501 votes cast at the straw poll, held at the Conservative Political Action Conference, with former gubernatorial candidate and retired Col. Mike McCalister at 30 percent, former U.S. Sen. George LeMieux with 24 percent and former steakhouse executive Craig Miller with 12 percent.

Bill Nelson, a Democrat, in the general election next year. Republicans are hoping to topple Nelson in their drive to take over the U.S. Senate, where Democrats currently hold a slim majority.
