How this race is decided
Staggered Senate
Senators serve four-year terms; half the seats are on the ballot each election.
Two-thirds quorum
Each chamber needs two-thirds of its members present to do business, so a minority holding more than a third of seats can block votes by walking out. Members with ten unexcused absences in a session cannot run for re-election (Measure 113).
