I was reading Phant2000's comment about what RP's agenda is, and it hit me all of a sudden why he flies first class all the time: Ron Paul has has both of his knees replaced with artificial knees. I am quite sure that in his situation, it would be agonizingly painful to fly stuffed into coach class with two artificial knees.
Heck, my knees hurt when I fly coach and both of mine are real.
What do you guys think? Plausible?
