It’s not clear to me from the Martinez ad what Denish did. Did she put up some kind of outlandish attack ad that backfired?
The very short version: the NEA put up an attack ad for Denish and against frontrunner Susana Martinez that featured a teacher who proceeded to badmouth Martinezs education strategy.
The only problem? Martinez happens to have been the prosecutor who put said teachers husband away for 23 years for kidnapping something that was not exactly brought up in the first campaign ad, and which certainly calls into question the true source of the teachers ire.
Naturally, the Martinez campaign is took advantage of the mistake.
