At the same time, it's noteworthy because the mayors don't have a whole lot of power or prestige. With no reelection, there are no Daleys in this bunch, and the mayoralty is almost always little more than a launching pad to bigger things. And yet they are opposing the presidency (though since most of the mayors are priístas, that's not a huge deal) and the nation's governors (who are mostly from the PRI). Furthermore, by the time the reform is actually implemented, most of the mayors won't even be in office, so it'll be someone else's problem, an assault on their successor's autonomy. One can only assume that many of the mayors probably have fantasies of being in their state's governor's mansion within a few years, in which case their opposition could actually reduce their power, should it prove successful.
