BROUN OUT…. Rep. Paul Broun (R) of Georgia is hardly a stranger to over-the-top, incendiary, right-wing rhetoric. But when he told constituents the other day that House Speaker Nancy Pelosi is a “domestic enemy of the Constitution,” it stood out.

“When I was sworn into the Marine Corps, I was sworn to uphold the Constitution against every enemy, foreign and domestic,” he said. “We’ve got a lot of domestic enemies of the Constitution and one of those sits in the speaker’s chair of the United States Congress, Nancy Pelosi.”

The Republican congressman was responding to a constituent who asked, “What would our founding fathers say about the mess that we have?” Broun reportedly responded by saying Americans have “lost a lot of freedom.”

He added, “I’m chairman of the Second Amendment Task Force fighting for Second Amendment rights. Those gun rights are actually critical to prevent treason in America.”

Now, I haven’t seen a full transcript, but it seems as if the congressman was calling the House Speaker an enemy of the Constitution in the same answer about access to firearms preventing “treason.”

So, here’s what I’m wondering: if Paul Broun really believes the Speaker of the House, third in line of secession succession to the presidency, is an enemy of the Constitution, why has he been so lackadaisical about it? Why hasn’t he filed charges or called for explusion? If the House leader is literally guilty of treason against the United States, why hasn’t he taken some legal, procedural steps to address this?

Maybe it’s because he doesn’t really believe his own nonsense, and Broun is just casually throwing around inflammatory, right-wing rhetoric because it keeps the GOP base happy. Indeed, his remarks came in late September, and for all I know, Broun wanted to give his fundraising a boost before the third quarter ended.

Or maybe House Republicans are holding a contest to see who can be the nuttiest. Calling the Speaker of the House an enemy of the Constitution would likely be worth quite a few points in the GOP’s internal pool.
