The PRI's (Lack of?) Responsibility

Jorge Chabat worries that when the PRI's short-term electoral interests diverge from those of Mexico as a whole, the former will win out: 

The coordinator of the PRI senators, Manlio Fabio Beltrones, warned the Finance Secretariat that it must choose between the ISR [Mexico's corporate profit tax] or the IETU [Mexico's corporate alternative minimum tax] but that both taxes together are unsustainable. Obviously, getting rid of taxes is very popular and it will help the PRI win votes. It won't resolve the problems of the nation but it will help the PRI maintain power. 

The same could happen on the issue of drug trafficking. For years the PRI dealt with this problem with same logic: it tolerated the problem so that violence wasn't generated with the goal of maintaining stability and a certain popular support. And in that regard we keep hearing voices that openly or implicitly call for a return to said policy, even from narcos. Nevertheless, a policy of that sort seems to resolve the problem, but it doesn't: it only postpones it and, in the end, aggravates it until eventually it becomes a crisis. 

The PRI has without a doubt a great responsibility as the primary force in the Chamber of Deputies. It would be nice if its conduct were up to the standard of the new role it must play.
