A new poll finds Donald Trump has a slight lead overall in California, though his popularity shifts from region to region.

That’s according to the latest Field Poll of 1,400 registered voters, out today.

As the Associated Press reports:

The poll released Thursday found 39 percent of likely GOP voters back Trump, while 32 percent support Cruz, 18 percent support Ohio Gov. John Kasich and 11 percent are undecided or plan to support someone else.

But the poll found significant regional differences, a noteworthy factor since 159 of California’s 172 delegates to the Republican National Convention will be decided by who wins each of the state’s 53 congressional district races.

Cruz leads in Los Angeles County and the Central Valley/Sierra areas, while Trump leads in other areas of SouthernCalifornia and the San Francisco Bay Area. Kasich has his strongest showing in the San Francisco Bay Area, the poll found.

The poll also reported that many of Trump’s supporters here are the same voters who backed Arnold Schwarzenegger for governor in 2003, according to AP.

For more on the topic, Take Two will be joined by Mark DeCamillo, director of the Field Poll. Listen live starting at 9 a.m. and check back shortly after the show for the full audio.
