(Bloomberg) Robert DiLorenzo’s e-mail account has been filling up with questions from friends about Liz Cheney ever since she formally declared her intention to challenge a fellow Republican, U.S. Senator Michael Enzi of Wyoming.

“It’s being greeted with confusion and mystery,” said DiLorenzo, a Wyoming attorney who co-founded the Big Horn Basin Tea Party. “I have seen her on Fox News, but we don’t really know enough about her and what she wants to do.”

Cheney, 46, a Fox News commentator who is the elder daughter of former Vice President Dick Cheney, will have her work cut out for her as she challenges a 69-year-old incumbent who is well-liked by both anti-government spending Tea Party activists and more traditional Republicans.
