well I am not ex pat (just about to become one in a few weeks), but I think my opinion counts as I am mexican, living in Mx City at the moment, and I can tell you is just business as usual, as you probably know we had a major set back in 1995 with the Ejercito Zapatista, and then some major protests on 2006 when Andres Manuel Lopez Obrador lost the presidency. Now, on the economic side of things, that is a different matter, and since economy here is heavly affected by the US economy, problems are likely to arise if things don't get better in the US. However, the energetic reform that is being currently discussed by the congress is bringing new hopes since as you probably know 60% of the government's income come from PEMEX. Rest is from the taxes they suck out of us... hope it helps.
