Here's one major difference in campaigning between U.S. politicians and Mexican, and entirely in Mexico's favor. From Milenio's interview with Silvano Aureoles Conejo, the left's candidate to be governor of Michoacán:
"Do you believe in god?
"Very little - I am not much of a believer."
That's it - no follow-up questions, no scandal, nothing. What a fresh breath compared to the constant groveling to the religious camps in the United States - how often does it happen that a major candidate to a major state simply states that s/he is not religious? And more so, that the candidate is not attacked for this?
