Eric Ehst, the Executive Director of Arizona's Clean Elections Institute has this letter in SitNews refuting arguments against a potential Alaska Clean Elections law. He parses a lot of the statistics that get thrown around in the debate over Clean Elections, which is useful information for public financing supporters, especially Alaskans who will be campaigning for this through August.This excerpt takes on the changes Clean Elections has brought about in terms of creating more heavily contested primary elections, which has effected incumbency reelection rates: She also says that incumbent reelection rates have remained stable at close to 100 percent. That's true by her definition, which only uses general election results. Most of Arizona's legislative districts have a heavy majority of voters of either the Democratic or Republican party and any incumbent who survives a primary challenge is virtually guaranteed reelection. Clean Elections has helped challengers knock off incumbents in the primary elections and by that measure the rate of incumbent survival is down from the 100 percent recorded in 1998, the last election before Clean Elections.
