This a big deal. The challenge now is to govern, which is a thousand times more difficult than winning an election. The left has had some success at governing, sometimes notable in fact. But we have had our share of failed experiences too. And that’s putting it nicely in some cases. Anyway, Obrador’s landslide will reverberate northward as well as southward And it comes at a time when the right in Latin American thought the wind was at its back.
