The Gallup Poll organization reports something that might give congressional incumbents plenty of pause as they campaign for re-election.

Listen up, Rep. Mac Thornberry.

It is that 46 percent of Americans — a record low — would vote to re-elect their member of Congress in 2014.

That’s down from 59 percent in 2012, according to RealClearPolitics.com.

Get this as well: It’s split evenly among Democrats and Republicans, at 18 percent for members of each party.

Why should this concern incumbents? Republicans in particular have shown this penchant for — as the late Texas state Sen. Teel Bivins used to say — “eating their young.” Tea party insurgents keep popping up to challenge “establishment Republican” incumbents. It’s happening in the 13th Congressional District — which Thornberry represents — with two challengers trying to outflank the incumbent on the right. The same is true in Kentucky, where Senate Minority Leader Mitch McConnell is being challenged by the tea party, as is Sen. Lindsey Graham of South Carolina.

It’s no secret that this appears to be the season of discontent with Congress. Polls show congressional approval in the low teens, which actually is a slight improvement from late in 2013, when it slid into the single digits.

How will this end up? It could end well for incumbents, but only perhaps when Congress can re-learn the art of legislating, which involves some compromise between the parties.
