“Republicans will seek a House vote next week admonishing a senior Democrat who they say threatened a GOP member’s spending projects in a noisy exchange in the House chamber, Minority Leader John Boehner said Friday,” according to the AP.

Their target is Rep. John P. Murtha, D-Pa., a 35-year House veteran who chairs the appropriations subcommittee on military spending.

Murtha, 74, is known for his gruff manner and fondness for earmarks — carefully targeted spending items placed in appropriations bills to benefit a specific lawmaker or favorite constituent group.

During a series of House votes Thursday, Murtha walked to the chamber’s Republican side to confront Rep. Mike Rogers, R-Mich., a 43-year-old former FBI agent. Earlier this month, Rogers had tried unsuccessfully to strike a Murtha earmark from an intelligence spending bill. The item would restore $23 million for the National Drug Intelligence Center, a facility in Murtha’s Pennsylvania district that some Republicans say is unneeded.

According to Rogers’ account, which Murtha did not dispute, the Democrat angrily told Rogers he should never seek earmarks of his own because “you’re not going to get any, now or forever.”

“This was clearly designed to try to intimidate me,” Rogers said in an interview Friday. “He said it loud enough for other people to hear.”

Now it’s true that there’s a House rule that prohibits “lawmakers from placing conditions on earmarks or targeted tax benefits that are based on another member’s votes.” Wouldn’t want anybody to oppose your earmarks just because you opposed his.

But really — after they lost control of Congress partly because of their profligate spending and their multiplying earmarks — this is what Republicans choose to fight over They’re going to draw a line in the sand on C-SPAN to defend Mike Rogers’s right to put special-interest earmarks in appropriations bills That ought to bring the independent and libertarian and small-government voters streaming back.
