Johnson points out how much more competitive political
races have been in Arizona than in California since Arizona
instituted redistricting reform. But that's only part of
the story, because Arizona also instituted "clean money"
public financing of campaigns for all its state offices in
2000. Incumbents in California almost always overwhelm
their opponents with money they've raised from special
interests. Arizona's election system, on the other hand,
provides matching funds when participating candidates are
outspent, resulting in a level playing field. This explains
why more legislative seats changed hands in Arizona in 2006
as much as redistricting does.
