Hillary Clinton has a double-digit lead in Colorado in a Monmouth University poll out Wednesday.

Clinton had 48% support of likely Colorado voters, while Donald Trump had 35%. Libertarian Gary Johnson had 5% and Green Party’s Jill Stein had 3%. Seven percent of those polled said they were undecided, and 3% have another candidate in mind.

Nine out of 10 self-identified Democrats said they supported Clinton (93%), while 3% said they were backing Trump and 1% said they wanted a third-party candidate. Self-identified Republicans are a bit more split — 78% backed Trump, while 9% supported Clinton, 4% said they liked Johnson and 3% supported someone else.

Clinton also held the lead with independent voters, 40% to Trump’s 28%. Johnson hit double digits with independents (10% backed him), while 5% went for Stein and 6% supported another candidate.

Clinton leads in almost every demographic, expect with men, with whom Trump holds a very slight (within the margin of error) lead.

Clinton had 56% support from women, to Trump’s 30%. Voters under age 50 prefer Clinton, 51% to 26%. She also led with Hispanic, black and Asian voters, 66% to 15%, and white voters, 44% to 38%. Her lead is smaller with voters over age 50, 45% to 42%, and Trump has a bit more support than her among men, 40% to 39% — although those numbers are both within the margin of error.

“Clinton does better among practically every demographic in Colorado than she does nationally. It is way too early to call, but if this dynamic holds, she could end up with the largest electoral margin for a Democrat here since 1964,” said Patrick Murray, director of the independent Monmouth University Polling Institute.

The telephone poll was conducted July 9-12 of 404 Colorado residents. The margin of error is plus or minus 4.9 points.
