National Democrats are growing increasingly anxious about the effort to oust California Gov. Gavin Newsom (D), urging voters in the deep blue state to get engaged ahead of the Sept. 14 recall election or risk a Republican taking office.

“It’s a big worry,” Sen. Chris Murphy (D-Conn.), who uses crowdsourced methods to help raise funds for Democratic candidates across the country, said of the race.

Several polls in recent days have shown recall supporters within striking distance of ousting the first-term governor, at least among voters who are considered most likely to cast a ballot. According to a survey conducted last week by the Berkeley Institute of Governmental Studies, Newsom would defeat the recall by a narrow 3-point margin, with 50% of the most likely voters saying they would retain the governor versus 47% saying they would replace him.
