Curious Campaigning from "Club for Growth"

Here's the setup.

What do you call a Congressman who:

"...was a leader in opposing amnesty in Congress and has an A rating from Americans for Better Immigration. He has a 100% record from the National Right to Life and Gun Owners of America[. and holds a] 92% rating from the American Conservative Union"?

Well, he's been called "the most liberal Republican Congressman from the South" by his primary opponent.

Apparently his 95% rating from Americans for Prosperity is not good enough for "Club for Growth", which is going to spend several hundred thousand against him in the primary. (!!)

Or....is it possible....maybe...that the opposition is due to Walter Jones' stand against the Iraq War?

You decide.
