Attorney Mike Lee (R), who is mulling a primary challenge to Sen. Bob Bennett (R), was making the rounds in Washington, D.C., this week. His visit included a sit-down with the anti-tax group Club for Growth on Wednesday to talk about the race.

The club, which has pegged Bennett as a “Republican in name only,— has been one of the three-term Senator’s biggest critics this cycle.

The group has slammed Bennett for his vote to pass the controversial Wall Street bailout bill and went after the Senator again this fall in a television ad and letter-writing campaign to potential GOP convention delegates for his efforts to promote the Healthy Americans Act, a piece of legislation he created with Sen. Ron Wyden (D-Ore.).

Lee “seems like an impressive guy and a committed fiscal conservative, but it’s too early to speculate about our next move in the Utah race,— club spokesman Mike Connolly said.

When contacted Wednesday afternoon, Lee declined to comment about his potential candidacy.

Three other Republicans, including conservative activist Cherilyn Eagar and former Congressional candidate Tim Bridgewater, are already in the race.
