As Hillary Clinton and Bernie Sanders prepare to make a final campaign push across California ahead of next week’s primary, a poll released Wednesday shows the Democratic contest tightening.

Clinton leads Sanders 49% to 47% among likely Democratic primary voters, according to the NBC News/Wall Street Journal/Marist survey. The poll’s margin of error is plus or minus 4.2%.

An average of several polls of California Democrats released in recent weeks shows Clinton with a lead of about 9 percentage points over Sanders.

Throughout the primary season, Clinton has captured the support of older voters and Sanders has netted the support of those much younger – a similar trend that has emerged here in California, according to recent surveys.
In the NBC/WSJ/Marist poll, Clinton leads Sanders 63% to 33% among likely voters ages 45 and older, while Sanders outpaces Clinton 66% to 30% among those 45 and younger.

Sanders, who has struggled to gain the support of minorities, leads Clinton 49% to 46% among Latinos, according to the NBC/WSJ/Marist poll.

Clinton and Sanders are scheduled to crisscross the state over the next several days as the June 7 primary nears. On Thursday, Clinton is set to deliver a national security speech in San Diego as Sanders campaigns in Northern California.
