Fox was a big disappointment in terms of his relationship with the US. Because he was the first non-PRI leader in 70 years, he felt he had to prove his bona fides by being doubly obnoxious to us. Also, on a personal level, Fox was a little flaky - anybody else remember the bizarre events with his live-in girlfriend, whom he suddenly married in 2001 and who announced a couple of years ago that she wanted to run for president this year? Her behavior had already made her less than popular, and they squelched that idea fast enough!
I was not suprised. He was just another corrupt Mexican President of a different party
