Donald Trump has erased the small margin he once trailed Ted Cruz by in California and now leads the Texas senator by a solid seven points in anticipation of their June 7, showdown.

A new Field Poll survey now finds Trump leading Cruz 39 percent to 32 percent, with Ohio Governor John Kasich bringing up the rear at 18 percent.

Just three months ago, before the GOP field had been wilted down to the final three candidates, the same pollsters found Cruz leading Trump 25 percent to 23 percent.

Trump Supported by Schwarzenegger Backers

At 54 percent, the poll found Trump garners strong support from among the same GOP voters who came out for Arnold Schwarzenegger in his 2003 run for governor.

Cruz, on the other hand, has strong support among Republicans in Los Angeles County, where he leads Trump 40 percent to 29 percent.

Despite all the favorable numbers, deeper analysis finds Trump still suffers from a serious image problem across the state, with 43 percent of participants insisting they have a negative image of him.

Cruz doesn't fare much better, with 39 percent of likely GOP voters revealing they have an unfavorable view of him.

Clinton Leading Among Democrats

On the Democratic side, former first lady Hillary Clinton leads Vermont Senator Bernie Sanders 47 percent to 41 percent. Over the last six-months, Clinton's support has held firm, while Sanders' popularity appears to be on the upswing.

Back in October, only 35 percent of likely Democratic voters indicated they planned to back his candidacy.

Among likely voters in the Democratic primary, 27 percent indicate they have an unfavorable view of Clinton, compared with 70 percent with a favorable impression.

In the case of Sanders, 75 percent of voters indicate they have a favorable view of him, against just 16 percent of voters who see him in a negative light.

Both Clinton and Trump also hold comfortable leads heading into the April 19, primary in New York. Polls show Trump sprinting out to more than half the vote and walloping Cruz by a 53 percent to 22 percent count. Kasich is an even more distant third at just 19 percent.

Among Democrats, Clinton leads Sanders by an average of 11 points.
