Hillary Clinton is a big favorite in California but has lost some support after FBI Director James Comey’s announcement last week that he might reopen an investigation into her email use while she was secretary of state.

A statewide poll released Tuesday by Southern California News Group and KABC/7 and conducted by the polling firm Survey-USA, also shows California voters poised to legalize recreational marijuana, require background checks for the purchase of some ammunition and slap a $2-a-pack tax on cigarettes.

A California proposition to abolish the death penalty is likely to be defeated, the survey found.

The poll also shows state Attorney General Kamala Harris far ahead of Rep. Loretta Sanchez, D-Orange, in the race for U.S. Senate.

The survey of 900 California voters was conducted Oct. 28-31 and is one of the first presidential surveys after Comey’s announcement. Some other new polls released Tuesday also show the race to be tightening nationally.

A tracking poll for The Washington Post/ABC News found GOP nominee Donald Trump beating Clinton by 1 point nationally.

Other reports that average multiple polls on Tuesday showed Clinton beating Trump by margins ranging from 2 to 6 points.

In the new SCNG/KABC poll, Clinton held a a 21-point lead over Trump in California, down from a 26-point lead she held in a poll released by the same group on Oct. 17. The change came largely among independents. Clinton’s lead dropped from 25 percent to 9 percent in that group.

Of the 747 early or likely voters polled, only 4 percent remained undecided; Clinton leads Trump by 17 points among those who haven’t voted. Libertarian candidate Gary Johnson would get 4 percent of the vote and Green Party candidate Jill Stein 1 percent, the poll found.

The poll also asked voters how they feel about the candidates and others.

Clinton was viewed extremely favorably or favorably by 51 percent of those polled, compared with 31 percent who feel that way about Trump. President Barack Obama polled at 62 percent in those categories.

Trump hit 64 percent in the unfavorable or extremely unfavorable categories, with Clinton at 46 percent and Obama at 36 percent.

The poll also looked at four key propositions.

Proposition 64, which would let individuals carry up to an ounce of marijuana and grow six plants for personal use – and create a multibillion dollar industry in the process – is favored 54 percent to 39 percent.

That gap is big enough that SurveyUSA believes Prop. 64 “appears positioned to become law.”

Proposition 56, which boosts cigarette taxes, is favored 60 percent to 33 percent. And Proposition 63, which would require buyers to register for ammunition and outlaw large-capacity magazines, is favored by 2 to 1.

Proposition 62, which would ban the death penalty in California, is headed for defeat, 50 percent to 39 percent.

Sanchez’s bid to win retiring Sen. Barbara Boxer’s seat in the U.S. Senate remains in serious jeopardy as the Orange County congresswoman failed to gain ground on the state attorney general, the poll found.

Harris enters the final week of the campaign with support from 47 percent of the likely and early voters polled. Sanchez is at 27 percent, and 26 percent of those polled remained undecided.

Harris has led throughout the race between two Democrats to replace Boxer, and she opened the lead considerably in October. In the group’s previous poll, she led 45 percent to 24 percent.

The number of voters still undecided about the race declined 5 percent in the polling released Tuesday compared with last month’s survey.
