When I look at the House Republican caucus, I tend to consider some of the higher-profile figures in an unwritten March Madness-style bracket. If we were to, for example, rank the GOP lawmakers with seedings, based on the degree to which they’re ridiculous, folks like Steve King, Michele Bachmann, and Louis Gohmert would be clear #1 seeds.

And while the competition would certainly be fierce for the other top seedings, it’s increasingly easy to argue that Rep. Trent Franks (R) of Arizona should at least be in the mix for a #2 seed.

Here he is this morning, on a fringe right-wing radio show, warning that the United States federal judicial system is “the biggest threat” to the nation.

Franks … argued that the courts are trying “inch by inch” to “take away our religious freedom,” and even argued that “if Mr. Obama appoints additional people to the Supreme Court that the Constitution itself will be fundamentally abrogated.”

So, in Trent Franks’ mind, another center-left high court justice or two will mean the end of the Constitution as we know it.

This comes on the heels of Franks arguing against an extension of the payroll tax break, despite the position of his party’s leadership.

Franks said he felt sympathy for Boehner, whom he said had been dealt “an impossible hand” politically by Obama.

“His pressure was in the force of his intellect given the totally untenable position he’s in with this president,” Franks said. “This president seems to think the Congress can repeal the laws of mathematics, and he’s an absentee chief executive.”

He wasn’t kidding.

This also, by the way, comes just a month after the Arizona Republican said if same-sex couples are allowed to get married, “it literally is a threat to the nation’s survival.”

Admittedly , it’s tough to keep track of all the instances in which Franks has been an embarrassment to himself. Remember the time he said African Americans were better off under slavery? How about the time he described President Obama as an “enemy of humanity“? Remember when he asked the House Sergeant at Arms to start looking for Muslim “spies” on congressional committees? Or when he claimed to speak for fallen American troops, saying the servicemen and women who were killed in war agree with him on economic policy?

And who can forget Franks’ talk about impeaching the president over defending the Defense of Marriage Act in court?

Put it this way, Franks is the only member of Congress to endorse Michele Bachmann’s presidential campaign. If that’s not enough to get him at least a #2 seed, what is?
