Hillary Clinton leads Donald Trump in four of the most diverse presidential battleground states, according to brand-new NBC News/Wall Street Journal/Marist polls.

Clinton is ahead of Trump by eight points among registered voters in Colorado, 43 percent to 35 percent; a combined 21 percent say neither, other or are undecided.

In Florida, which decided the 2000 presidential election, she’s up seven points, 44 percent to 37 percent; the rest are undecided or prefer someone else.

In North Carolina, a state Obama won in 2008 but lost in 2012, Clinton leads by six points, 44 percent to 38 percent.

And in Virginia, Clinton’s advantage is nine points, 44 percent to 35 percent.

“With 66 electoral votes at stake in these four states, Donald Trump is playing catch-up against Hillary Clinton,” says Lee Miringoff, director of the Marist College Institute for Public Opinion.

Colorado: Clinton 34 percent favorable, 62 percent unfavorable (-28); Trump 27 percent favorable, 67 percent unfavorable (-40).

Florida: Clinton 37 percent favorable, 58 percent unfavorable (-21); Trump 34 percent favorable, 61 percent unfavorable (-27).

Virginia: Clinton 37 percent favorable, 58 percent unfavorable (-21); Trump 29 percent favorable, 65 percent unfavorable (-36).

"The driving force behind voters’ choices is the negative impressions they have of both Trump and Clinton. Clinton’s single-digit lead in each of these states is due to her slight advantage in how voters perceive the two candidates," Miringoff adds.

Looking at the Four-Way Horserace
