A new set of polls released Wednesday by Quinnipiac University shows Hillary Clinton trailing three top-performing Republicans in the critical swing states of Colorado, Iowa and Virginia.

The Democratic front-runner lost in hypothetical head-to-head general election matchups against Wisconsin Gov. Scott Walker, former Florida Gov. Jeb Bush and U.S. Sen. Marco Rubio of Florida in all three states.

The results are as follows:

- Bush leads Clinton 41-36 in Colorado, 42-36 in Iowa and 42-39 in Virginia.

- Walker leads Clinton 47-38 in Colorado, 45-37 in Iowa and 43-40 in Virginia.

- Rubio leads Clinton 46-38 in Colorado, 44-36 in Iowa and 43-41 in Virginia.

Clinton led those candidates in the three swing states in similar Quinnipiac polls released in April.

While Donald Trump is way out in front of the rest of the GOP field in Republican primary polls - with 18 percent support in an average of the four most recent polls, compared to Bush's 13.8 percent and Walker's 10.8 percent - Quinnipiac decided not to put him in a general election matchup against Clinton.

Quinnipiac found that in all three states, voters gave Clinton low marks for honesty and trustworthiness, with 62 percent of Coloradans, 59 percent of Iowans and 55 percent of Virginians saying she is not honest or trustworthy.

A majority of voters in all three states said she does "not care about their needs and problems," and her ratings as a "strong leader" also went down.

"Hillary Clinton's numbers have dropped among voters in the key swing states of Colorado, Iowa and Virginia. She has lost ground in the horserace and on key questions about her honesty and leadership," said Peter Brown, assistant director of the Quinnipiac University Poll. "On being a strong leader, a key metric in presidential campaigns, she has dropped four to 10 points depending on the state and she is barely above 50 percent in each of the three states."
