Except for one minor detail...there is no head of the TSA. South Carolina Republican Sen. Jim DeMint has a hold on the appointment of a TSA chief.
Just another example of the rethugs decision that the best way to oppose Obama is to prevent the government from functioning any way that they can. They're perfectly happy to sacrifice the safety of air travelers if it will score them a few political points. Hell, they don't care how many Americans die in their quest to make Obama look like a failure. Refusing to confirm his appointments is one of their favorite tactics. While I'm not sold on the effectiveness of the TSA, the lack of a director certainly doesn't help.
It's one thing to have a difference of opinion, and oppose policies with which you disagree. But it's quite another thing to try to destroy the government in a fit of pique. The current rethuglican party are terrorist enablers, if not actually terrorists.
