A New York Times story Sunday explains why Indiana Republican U.S. Sen. Richard G. Lugar is likely to draw a re-election challenge in two years.

Here’s the mind-blowing paragraph:

Mr. Lugar’s recent breaks with his party have stirred the attention of Indiana Tea Party groups, who have him in their sights. “Senator Lugar has been an upstanding citizen representing us in D.C.,” said Diane Hubbard, a spokeswoman for the Indianapolis Tea Party. “But over the years, he has become more moderate in his voting.”

Hubbard puts it right out there — Lugar’s too reasonable for the tea party.

Clearly the tea party wants the opposite of “moderate,” which is: exaggerated, overdone, overstated, excessive, inordinate, undue, unreasonable, extortionate, outrageous, unconscionable, extraordinary, over-the-top, extreme or extremist and radical.

Hey, I didn’t say it. Blame a tea party representative and the dictionary.
