As Patrick Murphy and Marco Rubio both face primaries today that are expected to vault them into a head-to-head general election contest, Murphy is chiding the Republican incumbent for a vague answer Rubio gave CNN this week about whether he'd commit to serving a full six-year term if re-elected to the U.S. Senate.
Rubio told CNN's Manu Raju: "No one can make that commitment."
"You know now what the future is going to hold in your life personally or politically," Rubio continued. "I can commit to you this, if I'm running to a be a US senator, I'm prepared to let the US Senate be the last political office that I ever hold."
Murphy -- a two-term Democratic congressman from Jupiter expected to win today's primary -- was quick to pounce on Rubio's non-committal answer with a two-word pledge this morning:

Rubio's response on this topic has been consistent since he announced in late June that he'd changed his mind and would seek re-election to the U.S. Senate after his failed presidential bid. But by not committing to serve a full second term, Rubio has created a prime line of attack for Murphy, who argues Rubio is already jockeying to run for president again in 2020.
