DENVER — President Obama’s approval rating has plunged to an all-time low in the Rocky Mountains, according to a Quinnipiac University poll released Wednesday.

Colorado voters surveyed disapprove of his job performance by a margin of 59 to 36 percent. That’s not just a personal worst for Colorado—that’s “his worst approval rating in any state or national Quinnipiac University poll since he was elected,” according to the poll.

“President Barack Obama hits the rocks in the Rockies,” said Tim Malloy, assistant director of the Quinnipiac University Polling Institute, in a statement. “Republicans are singing, ‘Rocky Mountain low, Obama’s in the snow.’”

Among Republicans, the president’s disapproval stands at a lopsided 98 to 2 percent, while independent voters give him a thumbs-down by a margin of 65 to 27 percent. Mr. Obama still wins the approval of Colorado Democrats by 78 to 15 percent.

Mr. Obama captured swing-state Colorado in the 2012 election by a margin of 51 to 46 percentage points.

His plummeting approval numbers may be rooted in Colorado voters’ unfriendly opinion of the Affordable Care Act. The survey found Coloradans disapprove of the ACA by a margin of 56 to 40 percent.

Of those, 45 percent expect their health care to get worse as a result of Obamacare, while 18 percent say it will get better and 34 percent foresee no change.

The university surveyed 1,206 registered voters from Nov. 15-18 with a margin of error of +/- 2.8 percentage points.
