Louisiana Gov. Bobby Jindal has signed House Bill 292, a measure which will switch the state’s congressional elections to an open primary system, effective for the 2012 congressional elections.

Instead of the currently utilized three-tiered election cycle, wherein there is a party primary, followed by a party runoff, and culminating with the general election, HB 292 now advances the candidates with the top two vote totals from the primary to the November general election, regardless of party affiliation.

Jindal was under pressure from both political parties to not sign the bill into law, but he noted that the measure will potentially save the state more than $13 million during each congressional election cycle.
