I would say, “What else is new?” But, I think he has a very valid reason to be ticked off.

Via Politico:

Sen. Lindsey Graham is angry. He’s frustrated. He’s upset. In his own words, he’s “very dangerous.”

With the government shutdown now in its 12th day, and a possible U.S. debt default looming on Oct. 17, the veteran Republican was in the mood to lash out at everyone Saturday. President Barack Obama, House Republicans, Senate Democrats, Senate Republicans — they were all the target of Graham’s ire.

“The president is a pathetic leader. He’s only engaged in the last couple of days,” Graham said after the Senate blocked action on a Democratic plan for a “clean” debt-ceiling increase through 2014. “Every time you get close to getting a deal over here with our Democratic friends, they move the ball because some poll comes out. Our friends in the House apparently can’t muster the votes to send something over here to open up the government. So it’s dysfunction at every level.”

But the 58-year-old Graham wasn’t through venting yet. “You can blame us [Republicans], we’ve overplayed our hand, that’s for damn sure,” Graham said. “But their response, where the president and [Senate Majority Leader Harry Reid] basically shutting everybody out, and when you try to negotiate, they keep changing the terms of the deal … it’s very frustrating.”

“This is a very frustrated Lindsey Graham,” he added. “Which is a very dangerous thing.”

By Saturday afternoon, Graham suggested he may try to attach a version of Sen. David Vitter’s (R-La.) amendment ending health-care subsidies for lawmakers and congressional staffers to any Reid-McConnell agreement. Graham knows it’s a potential poison pill for any deal, but he is that unhappy right now.

“I am going to look at offering the Vitter language on anything that comes out of the Senate,” Graham told reporters. “If we’re going to screw up the whole country, we might as well throw ourselves in the mix.”

Graham had just come off the Senate floor where at least 15 senators huddled in bipartisan group discussing the current state of play and how to break the deadlock.

“There were how many, 15 people? There were 13 ideas,” Graham joked. “Two guys didn’t have an idea. They were the smart ones. They were the ones that kept their mouths shut.”

Graham then excused himself to go home and watch a football game.
