Hatfields versus McCoys, Mexican Politics Edition

The political dight du jour is Felipe Calderón versus Leonel Godoy, the governor of Michoacán. Or, more accurately, it's the Calderóns (who are from the same state) versus Godoy, and if you go back deep enough, it's the Calderóns versus the Godoys. Like any good feud, it has deep roots, what with the Federal Government arresting several officials in Godoy's state without prior warning, and with the standing warrant out for the arrest of his brother. And like any good feud, it spills over for often petty reasons; in this case, Godoy was mad because Calderón's sister, who is likely the PAN candidate for Godoy's post when he leaves office, went to a state event without Godoy's consent. Honor is being challenged. Expect fisticuffs.
