Republicans have narrow leads in two Senate races they must win to hold the majority, according to a new poll released Tuesday.

In Florida, Quinnipiac University’s survey finds Sen. Marco RubioMarco Antonio RubioRubio in Colombia to push for delivery of humanitarian aid to Venezuela On unilateral executive action, Mitch McConnell was right — in 2014 On The Money: Trump declares emergency at border | Braces for legal fight | Move divides GOP | Trump signs border deal to avoid shutdown | Winners, losers from spending fight | US, China trade talks to resume next week MORE (R) ahead of Rep. Patrick Murphy (D) by a slim, 2-point margin, at 49 percent to 47 percent. And in Pennsylvania, Sen. Patrick ToomeyPatrick (Pat) Joseph ToomeyOvernight Defense: Pick for South Korean envoy splits with Trump on nuclear threat | McCain blasts move to suspend Korean military exercises | White House defends Trump salute of North Korean general WH backpedals on Trump's 'due process' remark on guns Top GOP candidate drops out of Ohio Senate race MORE (R) leads Democrat Katie McGinty by a 49 percent to 45 percent margin, the poll found.

Democrats need a net gain of at least 5 seats to win 51-seat majority in the Senate and have placed high hopes on Pennsylvania, a state where their presidential nominee, Hillary ClintonHillary Diane Rodham ClintonRoger Stone shares, quickly deletes Instagram photo of federal judge on his case Barack, Michelle Obama expected to refrain from endorsing in 2020 Dem primary: report Why the national emergency?

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. 

The Quinnipiac survey also found that Sens.

Bennet leads local Republican county commissioner Darryl Glenn by a margin of 56 percent to 38 percent; Portman leads former Gov. Ted Strickland (D) by a margin of 54 percent to 41 percent. 

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.
