Weak. TSA isn't citing a poll about it's pat-down searches, which is what caused the recent uproar. The CBS poll has an overwhelming majority of respondents --- 83% of Republicans, 81% of Dems --- in favor of using +full body+ [em. orig.] digital x-ray machines.
(They'd have gotten I think a lower rate if they had worded it more aggressively --- "Some airports are now using imaging machines that allow TSA agents to electronically see through clothing" or the like.)
The problem we have is not that the TSA is lying; it's that people aren't well-educated about what these machines are actually doing. It's counterproductive to whine about numbers that the TSA is right to be citing; all you'd be doing is further obscuring the real issue.
