WASHINGTON — A new poll of likely Colorado voters gives an edge to Democrats Hillary Clinton and Michael Bennet but showed a lukewarm response to Gov. John Hickenlooper as a possible Clinton pick for vice president.

The survey by Harper Polling found that Sen. Bennet had a 46 percent to 40 percent advantage over Republican rival Darryl Glenn. Clinton, the Democrats’ presumptive nominee for president, was ahead 45 percent to 38 percent over presumptive GOP nominee Donald Trump.

The poll of 500 Colorado voters was conducted between July 7 to July 9 and mixed land lines and cellphones. The margin of error is about 4.4 percent.

Harper Polling is led by Brock McCleary, a former polling director at the National Republican Congressional Committee. The analytics website FiveThirtyEight gives Harper Polling a B-minus rating for methodology and historical accuracy.

Its findings are likely welcome among Democrats, particularly Clinton, who was in a statistical tie with Trump in Colorado in another recent poll. An analysis that ran with the Harper Polling survey noted that one reason for Bennet’s lead over Glenn is the Democratic incumbent’s higher name identification.

“Glenn receives less support from Republicans (78 percent) than Bennet does from Democrats (83 percent), a result of lower name identification for Glenn among party voters,” noted Harper Polling. “Bennet holds a comfortable lead among Democratic-leaning moderates (32-48 percent) but Glenn narrows his lead to just 4 percent among independent voters (33-37 percent).”

Less comforting for Bennet, however, is that it was a tie at 38 percent as to whether he deserves re-election versus the feeling that it’s time to give someone new a chance.

As for Hickenlooper, he wouldn’t add much to the Clinton ticket in Colorado, according to the poll. About 40 percent of Colorado voters would be more likely to vote for Clinton if she chose him, fewer than the 42 percent who would be less likely.
