According to the USA Today / Gallup poll, "Most are OK with the full-body scanners." Supposedly, 78% approve. The sample size? 542 adults, with no disclosure on how many of them actually worked for the TSA.
I ask, because according to a Reuters poll, 96% of people are against the use of these machines and the new pat-down techniques and will change their travel plans accordingly.
The sample size? 68,706, including me.
