Your speculation is wrong.
At Yale, Gary T. was a much bigger man on campus than George Bush. Trudeau wrote the same column under another name while he was an undergraduate for the Yale Daily News. Everyone read it. Then Trudeau hung around Yale for years (as a grad student) even while he was syndicated and becoming very famous in Watergate.
Jealousy from college is not Trudeau's motivation.
(Jealosy from college is not GT's motivation)
I don't disagree with your facts, but--with all due respect--perhaps your conclusion is incorrect. I say this because the SOB has everything most would want at the present time but he is obviously an unhappy, self-loathing, Bush-hating POS.
But then again, you could be right.
