Leopoldo Lopez

Caracas suffered another big power outage on Tuesday. The blackout shut down a hospital and a metro line and left large swaths of the Venezuelan capital without juice for much of the day.

One official response could be an upgrade of oil-rich Venezuela’s antiquated power grid. Another might be more spurious arrests of opposition politicians.

I’m betting on the latter.

That’s because the socialist government of President Nicolás Maduro seems much more skilled at finding scapegoats than at fixing problems.

Leopoldo López is a rock star among Venezuelans in South Florida. But in west Caracas he's the rich guy. And those contrasting images could affect the outcome of street protests playing out in Venezuela right now.

But first the obvious: This week’s arbitrary arrest of López, a top Venezuela opposition leader, is a reminder that President Nicolás Maduro’s already scant credibility is evaporating during the anti-government demonstrations that have swept his country since Feb. 12.
