Democrat Hillary Clinton is sitting on a 10-point lead over Republican Donald Trump in a head-to-head race for swing-state Colorado’s nine electoral votes, according to a poll of registered voters conducted this week by Fox News. The same poll shows Democratic U.S. Sen. Michael Bennet beating Republican challenger Darryl Glenn by 15 points.

In perhaps the survey’s biggest surprise, however, Libertarian presidential candidate Gary Johnson is running ahead of Trump among the state’s unaffiliated voters, although it’s by just a smidgeon. In the last presidential election in Colorado, when President Barack Obama won the state by about 5 points over Republican Mitt Romney, Johnson received 1 percent of the vote.

Clinton has a 44-34 percent advantage over Trump, a lead that shrinks by a point to 37-28 when the question was expanded to include Johnson and Green Party nominee Jill Stein. In the four-way contest, Colorado voters give Johnson 13 points and Stein 6 points.

Bennet trounces Glenn 51-36. The Democrat, who is seeking his second full term, performs best with women, Hispanics, those with college degrees and voters older than 45. But he beats Glenn, an El Paso County commissioner, across nearly every category, losing only among self-identified conservatives and white evangelicals.

It’s the third poll released this week that shows Clinton and Bennet leading their Republican opponents in Colorado, where the electorate is split roughly evenly between Republicans, Democrats and unaffiliated voters.

Broken down by self-identified party affiliation, Clinton leads among Democrats and unaffiliated voters, while Trump wins Republicans, but Johnson comes in second with independents, with 22-percent support, ahead of Trump’s 20 percent. (Clinton is ahead with 29 percent in that group and Stein scores 10 percent.)

Clinton does best among women, Hispanics, voters with a college degree and those who say they’re extremely interested in the election. Trump wins among white voters without a college degree, rural residents and white evangelicals.

Democratic Gov. John Hickenlooper scores a 55-percent favorable rating, just ahead of President Barack Obama, who gets 54 percent.

The two major-party presidential candidates, however, are mostly disliked by Colorado voters, although Trump comes out ahead by that measure. Fifty-eight percent of respondents view Clinton unfavorably, while 68 percent think poorly of Trump.

By a wide margin, Colorado voters say the economy is an important issue this year, followed by nominations to the U.S. Supreme Court and terrorism, which tie for second-most important topics.

More voters say they think Clinton has the temperament to serve as president, is qualified to be president, is a strong leader and “cares about people like you,” while Trump just edges out Clinton by 1 point when asked which of the two is “honest and trustworthy.” A whopping 41 percent of voters say neither fits that description, however.

The poll was conducted jointly by Democratic firm Anderson Robbins Research and Republican firm Shaw & Company Research over both landlines and cell phones from July 9-12. Pollsters interviewed a random sample of 600 registered voters and reached an additional 30 randomly selected Hispanic voters to reduce the margin of error for that group, using bilingual interviewers when appropriate. The margin of error was plus-or-minus 4 points.
