Notes: "Same-party runoffs” refers to the percentage of districts where two candidates of the same party will face each other in the fall. "Winner > 50%” is the percentage of top vote-getters who received more than half the vote. "Average gap” is the gap in vote share between the first- and second-place finishers, and second- and third-place finishers, respectively. The gap in vote share between the second- and third-place finishers shows the share of votes required to change the top two finishers. The 2012 numbers differ slightly from those reported in California’s Electoral Reforms: How Did They Work? because the numbers in that fact sheet reflected preliminary election returns.
