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 RubioGOP leaders hesitant to challenge Trump on Saudi Arabia On The Money: Treasury official charged with leaking info on ex-Trump advisers | Trump to seek 5 percent budget cut from Cabinet members | Mnuchin to decide by Thursday on attending Saudi conference Mnuchin to decide by Thursday whether to attend Saudi conference 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 ClintonMueller's team asking Manafort about Roger Stone: report O'Rourke targets Cruz with several attack ads a day after debate GOP pollster says polls didn't pick up on movement in week before 2016 election MORE, has consistently led Donald TrumpDonald John TrumpTrump renews attacks against Tester over VA nominee on eve of Montana rally Trump submits 2017 federal income tax returns Corker: Trump administration 'clamped down' on Saudi intel, canceled briefing MORE in polls.

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.
