I don't even think it's that. I think Bush is catering to Fox for other reasons and it bothers me what those other reasons might be. Some Mexican told me today that the previous president of Mexico --Salinas de Gotari (the one whose brother in law was murdered by his brother in some kind of drug lord thing) is back in Mexico and that he had helped put Fox into office. Fox also denied asylum to those 21 Cubans recently ---and even had Castro send in his police force after them, so I don't think Fox is on the side of good or freedom at all.
I don't know squat about Fox. But I'm willing to learn. Do you have any links? There's nothing in the papers, at least those that I've seen.
