Top GOP presidential contenders have a solid lead in Colorado over key Democrats vying for the White House, according to a Quinnipiac University Poll released this morning.

Hillary Clinton, Bernie Sanders and Vice President Joe Biden were all defeated in separate match-ups with Marco Rubio, Jeb Bush and Wisconsin Gov. Scott Walker.

The strongest Republican candidate showing in Colorado in previous polls was Rubio, and in today’s showing he still takes down Clinton 46-38, Biden 49-35 and Sanders 46-35.

However, Walker gained the largest support over Clinton 47-38, and defeats Biden 48-36 and Sanders 44-36.

“Hillary Clinton’s numbers on honesty and trust may border on abysmal but Wisconsin Gov. Scott Walker, the GOP front runner, is still battling a name recognition handicap,” said Tim Malloy, assistant director of the Quinnipiac University Poll. “Do Colorado voters trust Hillary? No, they do not. Do they think she cares about their needs? No they do not.”

Bush defeated all three Democrats, although his showing was not as strong as Walker and Rubio. In the head-to-head with Clinton, Bush polled 41 percent over Clinton’s 36. With Biden, Bush took 45 to Biden’s 36 percent. Against Sanders, Bush wins 43 to 37.
