The one crimp in the hope for his resignation is that someone has to go to jail for this. I mean PMITA jail for years, not just some petty 30-day country club thing. I mean life sentence for Brian Terry’s death, which of course means out in 15 years on good behavior - at which point he gets extradited to Mexico for consecutive death penalties for 149 accessory-to-murders, which get negotiated down to life solitary in a country which equates that cell with an offal cistern.
This is going to get very, very ugly. That bus isn’t going very far with all the people about to get thrown under it.
