With Hillary Clinton holding on to a steady six point lead in the latest polls, Democratic challenger Bernie Sanders is set to unveil his first paid television ads in the state of California.

Campaign organizers have branded a new 30-second spot as "$27," a figure that's said to represent the average contribution made to the liberal-minded Vermont senator by his growing throng of supporters.

"I think it's the best $27 you can spend," one voter says in the ad.

Meanwhile, with just weeks remaining before voters go to the polls in California on June 7, a new Field Poll survey finds Clinton leading Sanders 47 percent to 41 percent.

Clinton Support Holding Firm, Sanders' own the Rise

The silver lining for Sanders is while support for Clinton has held firm since the poll was last taken in January, he has seen his own support climb from 35 percent to its now high of 41 percent.

Among likely voters, 27 percent of Democratic primary voters indicate they have an unfavorable view of Clinton, compared with 70 percent with a favorable impression. Sanders was rated unfavorably by 16 percent of voters, compared with 75 percent view him favorably.

Clinton was recently in California for a pair of high-dollar fundraisers with film star George Clooney, a development that drew the attention and backhanded criticism of some of Sanders' biggest supporters.

"It's a very powerful statement about what Bernie's campaign is about," Tad Devine, the campaign's chief strategist said of Sanders' different approach to fundraising. "He's trying to create a political revolution in America, not just by talking about these issues, but by acting on them."

Trump Holds Edge Over Cruz

On the Republican side, pollsters found GOP frontrunner Donald Trump leading Texas Sen. Ted Cruz 39 percent to 32 percent with Ohio Gov. John Kasich at 18 percent.

As recently as in January before the Republican field was significantly shrank, the same poll found Cruz leading Trump 25 percent to 23 percent.
