The Senate Democrats’ campaign arm is pulling the remaining money for TV advertising out of the Florida Senate race with three weeks until Election Day.

This week, the Democratic Senatorial Campaign Committee (DSCC) canceled its remaining ad reservations in support of Rep. Patrick Murphy (D-Fla.), a DSCC official confirmed. The move was first reported by the Miami Herald.

Earlier this year, the DSCC reserved $10 million to help Murphy, who faces an uphill battle against Sen.

The committee has previously shifted money out of the state to invest more heavily in late-breaking Senate races, such as in Missouri and North Carolina, where the incumbent GOP senators look increasingly vulnerable.

The committee has also pulled dollars from the Ohio Senate race, where GOP Sen.

Ted Strickland (D).

The final cancellation comes a day after the Senate debate between Rubio and Murphy, but DSCC spokeswoman Sadie Weiner told the Herald in an email that the decision was reached prior to Monday night’s bout and was "absolutely not a reaction to the debate. Patrick did incredibly well."

Rubio has led every survey in RealClearPolitics polling roundup since early July, though the most recent Quinnipiac University poll released Tuesday shows a much tighter race, with the GOP senator ahead by only 2 points, within the margin of error.
