Plans for a Coup against Fernando Lugo?

Maybe Fernando Lugo's not as safe as I thought:

Latin American leaders have rallied behind Paraguay's new president, Fernando Lugo, after he said he was the target of a possible coup plot.[... Lugo] has accused retired general Lino Oviedo and former president Nicanor Duarte of involvement in the alleged conspiracy. Both have denied this.

I don't really know what to make of this, honestly. Oviedo and Duarte both deny Lugo's accusations, claiming that Lugo's just making such claims for "political purposes," while Lugo is claiming he has "evidence of the meeting and plot and said all Paraguayans need to be on alert for coup attempts by "antidemocratic and retrograde” elements."

It's a really weird story, and a little unsettling. Certainly, his decision to sack the top military commanders could and probably did ruffle some feathers, so it gives some substance to his claims about Oviedo and Duarte. Oviedo and Duarte may be right; this may be a political ploy. If it is, though, it's a ploy that doesn't make much sense for Lugo: he is still in his honeymoon period, and he doesn't really have any major opposition from the electorate or domestic troubles yet. What's more, Lugo has never been a demagogue, and I'm not sure why he'd start now. If this is true, it's unsettling; hopefully more info will come to light, and Lugo will be able to complete his still-nascent presidency.
