We'll see what happens over the next few days. If a significant number of people opt out of the scanners resulting in noticeable delays it will be interesting to see how the average flyer reacts.
If the average flyer sides with the protestors and blames the TSA, then there is hope. If the average flyer complains about the protestors and says something like "I know I know it's not right, but I have to get to Aunt Edna's and I don't want to get stuck in the airport so please do what you're told" well then that's another story entirely.
This will not play out over a few days.
The fruits of this garbage will come home to the democrats in months and years.
