Hillary Clinton may have a tough race on her hands.
A new Quinnipiac University poll finds the former secretary of state trailing former Florida Gov. Jeb Bush, Florida Sen. Marco Rubio and Wisconsin Gov. Scott Walker in hypothetical head-to-head matchups in the crucial swing states of Colorado, Iowa and Virginia.
According to the poll, released Wednesday: Clinton trails Rubio by a margin of 38-46 in Colorado, 36-44 in Iowa and 41-43 in Virginia. Bush tops Clinton by a margin of 41-36 in Colorado, 42-36 in Iowa and 42-39 in Virginia. Against Walker, Clinton trails by 38-47 in Colorado, 37-45 in Iowa and 40-43 in Virginia.
The numbers represent a decline for Clinton against the possible GOP opponents.
Underlying Clinton’s slip is an erosion in her favorability numbers.
In Iowa, 45 percent of voters viewed her favorably in an April 9 survey from the university, while a similar number, 47 percent, viewed her unfavorably. By July, just 33 percent viewed her favorably, with 56 percent viewing her unfavorably. Clinton has faced questions, especially over her use of a private email address to conduct government business at the State Department, as well as foreign donations to her family foundation.
