The maps voters approved with Proposition 50 make it likely that five of California's GOP-held congressional seats could be won by Democrats in next year's midterm elections. They also bolster the re-election chances of three Democrats currently holding office in now-competitive districts.

Proposition 50 would allow California Democrats to replace the state’s congressional maps with ones the party hopes will help them to flip five GOP-held seats.

A University of California Berkeley/IGS Poll suggests 60% of likely California voters support Proposition 50, while 38% oppose it. The breakdown was highly partisan, with 93% of Democrats saying they would choose "yes" and 91% of Republicans choosing "no."

A Texas congressman who a judge blocked from challenging an effort in California to redraw the state’s congressional maps is trying once more—joined this time by a California representative.
