Ciro Gómez Leyva's column is following up on some very interesting polling in Mexico City: Just a couple of months ago, PRI's Beatriz Paredes Rangel was number one in the polls to be the next mayor of Mexico City, and in the process expected to pull a lot of votes for Enrique Peña Nieto as well.
Yet due to various factors - some extremely ugly infighting and fighting (literally) in the Mexico City PRI, which has some of the worst scoundrels in Mexican politics in its ranks, the ability of the left to pull together and present a great candidate, etc - PRI is plummeting again in Mexico City.
A recent poll gives Mancera 43, with only 16 percent (!) for Paredes. This is quite spectacular, and as Gómez Leyva points out, very, very bad news for PRI and Peña Nieto.
