From listening to my co-workers and friends, many of whom are the "once a year" travelers, I'll take issue with the above statement.

For the great majority, their attitude toward the TSA has moved from one of total support to one of realizing that most of the checkpoint hassle is useless; the liquids nonsense and "all shoes off" were the turning point.

The unfortunate thing is that these people won't do anything to make their feelings known.

OTOH, many of the above are formerly "dyed in the wool" Republicans who are planning to vote for the Democrat this year. However, that has come about as a result of the economy and the war.
