The California State Legislature currently has a Democratic majority, with the Senate consisting of 24 Democrats, 13 Republicans, and 3 vacancies; and the Assembly having 52 Democrats and 28 Republicans. Except for the period from 1995 to 1996, the Assembly has been in Democratic hands since the 1970 election (even while the governor’s office has gone back and forth between Republicans and Democrats). The Senate has been in Democratic hands continuously since 1970.
Gerrymandering works.
Thanks, but ouch. Almost a 2-to-1 dominance. Ouch.
