Again, I agree he was total crap, just not nefariously behind everything bad. Except Veracruz, that's worth bashing the hell out of him for.Federal troops could have intervened earlier. Federal legal machinery (14th Amendment) existed to cool-down the situation. Wilson did nothing. Credit Congress with finally fixing that mess.
EDIT: Anyway, I think we've exhausted this tangent that started because I probably misread your post and thought you implied Wilson's mistake in Mexico was in supporting the Constitutionalists at all, not his terribly heavy-handed response to what was essentially a bandit raid which I think is what you intended to suggest.
