Guatemala doesn't count?

From Jorge G Castaneda's opinion piece on Good times down Latin America's way up at Al Jazeera.

Three elections were held in Latin America in 2011. Two - in Argentina and Peru - went well; the other - in Nicaragua - was marred by egregious fraud and heavy-handed government intervention in favour of the incumbent. Still, two out of three is not bad in a region where, previously, if elections were held at all, disputes about the outcomes were the norm.

You can say that Guatemala's election wasn't as important, regionally speaking, as those in Nicaragua, Peru, and Argentina, but ya gotta include it. Maybe he's got something against Guatemala.

So, what's the reason why the United States is only sending its Peace Corps Director (to check out country conditions for himself?), US Ambassador to Guatemala, Senator Mary Landrieu, and the USAID Assistant Administrator for Latin America to Otto Perez Molina's inauguration? 

Like Castaneda, does the US not place much of a priority on Guatemala? Or, are we sending low-level dignitaries (no offense) because we don't want to have the big guns standing with an alleged war criminal? Has anyone heard who, if anyone, is going to Nicaragua?
