At the risk of lazily thinking that more similarity to the US system implies greater effectiveness, I think the broad strokes of the PRI's scheme are sound. I suppose a lot would depend on how, along the continuum from perfunctory consent on one side to raking nominees over the coals as a matter of course on the other, the senate actually practiced its prerogative, but I like the fact that the senatorial approval in the States offers potential cabinet officers an incentive to stay clean. Such a mechanism could also serve as a filter of conflicted cabinet officers, as many people alleged that Juan Camilo Mouriño was after his family's contracts with Pemex were discovered last year. In that sense, senatorial approval would be a baby step in the direction of cleaner government, one of thousands needed in Mexico. Plus, this PRI plan not as unwieldy or as underhanded as the past scheme to superimpose a prime minister on the presidential system.
