Sen. Marco Rubio (R-FL) hedged his bets on what his political future may hold in a Tuesday interview with CNN, saying he just wasn’t sure if he would be able to stay in office for a full six-year Senate term if re-elected.

“No one can make that commitment because you don’t know what the future’s gonna hold in your life personally or politically,” Rubio said.

While this comment suggested that the former 2016 presidential candidate might be open to another run for the White House, Rubio said he was “prepared” for his political career to come to an end in the Senate.

“I can commit to you this, and that is that if I am running to be a U.S. senator, I am fully prepared to allow the U.S. Senate to be the last political office I ever hold,” he said.

Rubio made similar claims after losing by double-digits in his home state during the presidential primary and suspending his presidential bid. The the 45-year-old junior senator testily told reporters that he said he was content to become a “private citizen” come January 2017, before recanting that and entering the race to keep his seat.

TPM’s PollTracker Average shows Rubio leading GOP primary opponent Carlos Beruff 63.3 percent to 19.3 percent ahead of Tuesday’s Florida Senate primary. The PollTracker Average also shows Rubio with a slight edge over his likely Democratic opponent, Rep. Chris Murphy, 44.1 percent to 41.7 percent.
