The November-December 2011 CEP poll has nothing but bad news for Sebastián Piñera, who at 23 percent approval is one of the least liked presidents in Latin America. Chileans don't like much of anything he's doing. One consequence is that more Chileans than ever do not identify with any existing party coalition. That has been one of Piñera's "accomplishments."
This is important in the context of the recent reform that makes registration automatic and voting voluntary. These "ni nis" (ni gobierno ni oposición) will be now be voting. However, there is a major disjuncture because the country still has the binomial electoral system at the legislative level. This means a load of new voters in an antiquated system that precludes new parties from becoming involved.
As it happens, the CEP poll also shows that support for the binomial system has been dropping hard since Piñera took office. Sixty percent think it should be changed, while only 17 percent think it should be maintained. Depending on how it is done, that reform could really shake up Chilean politics.
