We review the principal political events of Mexico in 2006. The most competitive presidential election in Mexican history left without much coverage the other elections that took place during the year (to renew both chambers of the federal Congress, 6 governorships, 12 state congresses, and 566 county councils in 12 states) and removed from the agenda many policy issues. Even if the failure by the defeated candidate to concede victory to his adversary in a nasty post-election dispute would appear to leave the nascent Mexican democracy in a bad condition, there are many more indicators of a healthy and working democratic system. Because this is the first review in what will become a yearly exercise, we include some relevant information previous to January 1st, 2006.
