Democrats are seeing warning signs after a new poll showed Hillary Clinton losing three swing states and deep in negative territory on questions of character.

One Democratic strategist who spoke on condition of anonymity described the poll results as “the canary in the coal mine.”

“The poll, from Quinnipiac University, surveyed voters in Colorado, Iowa and Virginia. President Obama won all three states in both of his presidential election victories, but they went for former President George W. Bush almost as uniformly in 2004 and 2000.

When the pollsters tested Clinton against leading Republican contenders Sen. Marco Rubio (Fla.), former Florida Gov. Jeb Bush and Wisconsin Gov. Scott Walker, she lost every state to every opponent.

Among the most alarming findings, from a Democratic perspective, was the indication that Clinton, widely considered the party’s front-runner, would lose Colorado by 9 points to Walker and would lose by at least 6 points to any of the three candidates in Iowa.
