Where’d you find the breakdown of the Mexican vote in the US?
The Mexican government has the results available, but by the Mexican state the absentee ballots were cast for, not the US jurisdiction from where.
PAN seems to have cleaned up with the US vote.

It's taking forever to load, so I haven't gone thur it, but my recollection is that yes, PAN won overwhemingly among Mexicans in the U.S., and that PAN got the bulk of their votes from regions of the U.S. that overwhemingly favor commie Democrats (Los Angeles, Chicago, etc.) There's probably a good case to made that the “far left” PNR would have won that election if not for the extra boost of votes PAN got from Obama loving Mexicans here. Certainly it was down to the wire in Mexico and each party won about half of Mexico's states.
Considering Mexicans often illegal vote in our elections and affect the outcome (Loretta Sanchez anyone?), turnabout is fair play. I wonder if there's a way to claim to be an “undocumentary migrant” and get them to mail us some Mexican ballots for the next election? We might foist some decent pro-law abiding politician on them. That is assuming they have anyone decent running (most of the anti-illegal alien politicians are commies, though someone once mentioned there was a “Zell Miller type PRI congressman” who vocally opposed open border policies.
