While Republicans are worried about Toomey, they are more confident about Florida. The Miami Herald reported on Tuesday that the Democratic Senatorial Campaign Committee is pulling resources from the state, which could be a sign that they no longer think Murphy can win.

Quinnipiac surveyed more than 600 likely voters in each state on land lines and cellphones with margins of error at about 4 percent. The polling took place from Oct. 10 to 16.
