Clinton leads Trump by 25 points in California, SurveyUSA poll shows

LOS ANGELES (KABC) -- Democratic presidential nominee Hillary Clinton leads by 25 points in California against Republican nominee Donald Trump, according to the latest exclusive Eyewitness News/Southern California News Group poll conducted by SurveyUSA.

But the numbers may change because 87 percent of people who participated in the poll were interviewed before news of Clinton's pneumonia diagnosis.

In the poll, Clinton appears far ahead of Trump, 57 percent to 32 percent, which are margins similar to when Barack Obama defeated Mitt Romney and John McCain, according to the survey.

In 2008, Obama carried California by 24 points against McCain and by 23 points against Romney in 2012.

The poll also showed that Clinton leads by 30 points among women, especially with single mothers. She also leads among white, Asian, Latino and African-American voters. But Clinton trailed by 4 points against Trump when it came to votes from gun owners.

When people were asked on their opinions being extremely favorable to extremely unfavorable or unsure of the candidates, only 13 percent of those asked had an extremely favorable view of Trump, while 19 percent said favorable. As for Clinton, 19 percent had an extremely favorable review, while 33 percent said favorable.

Many of those asked had extremely unfavorable reviews for each candidate: Trump at 52 percent and Clinton at 31 percent.

The poll also showed that Democrat Kamala Harris leads against Democrat Loretta Sanchez in the election to replace retiring state Sen. Barbara Boxer.

SurveyUSA spoke with voters about four of the 18 propositions on the ballot, which include the legalization of recreational marijuana and a stricter gun regulation.

Voters appeared to favor Proposition 56, which is a $2 tax increase on cigarettes; Proposition 63, which outlaws large-capacity magazines and requires background checks for ammunition purchases; and Proposition 64, which would regulate and tax recreational marijuana.

The only proposition that may fail in the election, according to poll results, is Proposition 62, which would end the state's death penalty and replace it with life-in-prison sentences.

SurveyUSA interviewed 900 California adults, and of those, 782 were registered to vote. Of those registered voters, 678 were considered likely to vote in the general election.
