Here are the current totals from Ecuador's Centro Nacional de Eleccciones:
I'll come back to the point I made in an op-ed in February, which is that the left/right thing isn't necessarily a helpful way to understand what's going on. Fundamentally, this is mostly about the Ecuadorian right's inability to craft an effective message after years of demonizing Rafael Correa. Voters look to who is going to solve their problems. If we want to see this in left/right terms, the best way is to consider it an utter failure of the right. As in the United States, too much of the Latin American right is so immersed in its dislike for the incumbent that it spends no time actually developing policy alternatives.
If there is a lesson here, it's for the right in Bolivia and Venezuela. If you want to win (and in Venezuela this is predicated on actually having elections, I know, but it was a problem even when elections were held) then find ways to appeal to people. And even if you do win, you have to govern.
There will be other stories too, such as the 6% who voted null, and of course the right's dispute of the results. Unfortunately, though, I expect the "big win for the Latin American left" to dominate and people will cling to the "pink tide" imagery.
