The presumptive Democratic nominee Hillary Clinton holds a small 5-point lead over Republican challenger Donald Trump, according to the June CNBC All-American Survey, with a large chunk of the voting public remaining undecided. The poll of 801 registered voters conducted June 11-14 shows Clinton with a 40 percent to 35 percent lead, but the poll's margin of error is plus or minus 3.5 percentage points.

Pollsters for CNBC say the survey shows a tight race with 25 percent undecided, including 14 percent who right now choose "neither" candidate."It's the hallmark of a campaign with high negatives around these candidates," said pollster Micah Roberts with Public Opinion Strategies. The poll was conducted by POS from the Republican side and Hart Research Associates from the Democratic side.But both pollsters pointed to one group that could increase Clinton's margin.

The survey shows that 20 percent of voters who had supported Democrat Bernie Sanders currently choosing neither candidate. "I've seen nothing to suggest that Sanders supporters won't break in favor of Clinton,'' said Jay Campbell, Hart Research's senior vice president. He points out that Sanders supporters who have made their decisions back Clinton about 6 to 1.
