The ruling Sandinista party of Nicaragua is seeking to lift the current restrictions on presidential reelection, and to return to election of the president by plurality.
This was utterly predictable. Daniel Ortega has become the new strongman of Nicaragua, and has been president off-and-on since the revolution of 1979. He is 67, giving him plenty of years left, assuming continued good health. Did anyone think he would contemplate voluntary retirement?
The rules have been changed before. Ortega remains in office now thanks to a favorable court ruling that allowed him to run for reelection in 2011. His return to office in 2007, following a hiatus of several years, was facilitated by a change in the rules to a variant of qualified plurality: winning a plurality of just 40% of the vote would suffice, but so would as little as 35% if the runner-up was at least five percentage points behind. (For the 1996 and 2001 elections, the requirement was 45%, as part of an earlier pact between the Sandinistas and the opposition.)
If the current proposal passes, it will return Nicaragua to the provisions that prevailed in the original 1987 constitution enacted in the early post-revolutionary period when the Sandinista Front was still dominant: plurality election, and unlimited eligibility for reelection.
Barring an unexpected internal split, the caudillo will get what he wants. Sandinistas won more than two thirds of the seats in the unicameral legislative assembly in 2011.
