Washington (CNN) - After six terms in the Senate, Indiana's Richard Lugar finds himself the latest target of the tea party movement's desire both to have more influence over the policy agenda in Congress and to make the Republican Party more conservative.
"He's an old RINO Republican," Jim Bratten, an Indiana coordinator for Tea Party Patriots, said of Lugar, meaning he's a Republican in name only. "He's been there [in Washington] for over 36 years, but gradually he's gotten closer and closer to the left, and he seems to want to compromise on things that are principle that you really can't compromise on."
