Nick requested to see CA districting under the shortest splitline algorithm.
In 2004, not one of CA’s 173 state legislative and federal congressional seats changed party-hands. In 2002, every incumbent won re-election, on average with 69% of the vote. California may be the new gerrymandering champion, perhaps even worse than Illinois and Texas, but unlike them its gerrymandering is “bipartisan” that is, arranged by agreement among the Democrats and Republicans to “design their own districts” to make every office holder “safe.”
