Californians are voting on a ballot initiative, "Proposition 50," to determine if the state will adopt a new congressional map that redraws five districts to be more Democratic-leaning, potentially allowing Democrats to flip them in the midterms.

Voters will decide if California’s voting districts should be redrawn to help Democrats flip up to five House seats.

Today is the last day to vote on California’s special election Proposition 50. The measure would temporarily redraw the state’s congressional maps to favor Democrats in five key districts , bypassing California’s independent redistricting committee.

According to a poll released last Thursday from the UC Berkeley Institute of Governmental Studies, co-sponsored by the LA Times, six out of 10 likely voters support Prop. 50, the Nov. 4 statewide ballot measure that would redraw California’s congressional districts and give Democrats a boost toward regaining control of the House.

While Tuesday's elections don't involve the presidency or control of Congress, there are plenty of intriguing statewide and local races and ballot measures to watch.
