▸ The rules // Governors

Senate rules, unchanged
This number comes from the same polling average, fundamentals, blend and error sizes as the Senate races, with the state's last governor election in place of the last Senate result. Governor results track presidential lean less tightly than Senate results, so the fundamentals can miss where a popular incumbent crosses party lines. There is no governor backtest yet.
