Hillary Clinton holds a three-point lead over Donald Trump in the latest Fox News Poll, which also finds support for the controversial republican presumptive nominee drop by six points over just the last three weeks.

Overall, Clinton now leads Trump 42 percent to 39 percent with 85 percent of all voters insisting "more than usual" is at stake in this year's election, a 15 percent increase over the number of voters who felt that same way in 2012.

The poll was conducted over a 96-hour period when Clinton scored enough delegates to be officially be declared the presumptive Democratic nominee. Just days before, the same poll found Trump leading by three points (45 percent to 42 percent), but since then support for him has fallen by three points among Republicans and a staggering 11 percent among independents.

Research shows Clinton leads among African Americans (+76), unmarried women (+34), women (+18), lower-income households (+14) and voters under age (+13).

On the flip side, Trump leads among white evangelicals (+42), whites without a college degree (+25), whites (+16), men (+15) and independents (+5).

More than 8-in-10 Clinton supporters insist there is no chance (57 percent) or only a small chance (24 percent) they will not stick with the former first lady, while 80 percent of Trump's overall backers maintain the same thing.

In addition, 69 percent of all voters view Clinton as qualified to be president, while only 47 percent of voters feel the same way about Trump. Clinton is also rated higher on having the knowledge (+33 percent) and temperament (+27) to be commander in chief.

Pollsters also found Sanders' overall popularity continues to swell with 54 percent of voters viewing him favorably, good for an 11-point lead (49 percent to 38 percent) nationally.

Sanders recently vowed to remain in the race until the Democratic National Convention in Philadelphia in early July.
