The Florida senator in a Wall Street Journal editorial says he won't vote to raise the debt limit when the current ceiling is hit sometime later this year.
"I will vote to defeat an increase in the debt limit unless it is the last one we ever authorize and is accompanied by a plan for fundamental tax reform, an overhaul of our regulatory structure, a cut to discretionary spending, a balanced-budget amendment, and reforms to save Social Security, Medicare and Medicaid," he writes in the piece which will appear in tomorrow's WSJ.
Rubio -- who this week is raising his national profile -- isn't the first conservative to balk at raising the debt. Penn. Republican Sen. Pat Toomey said he wouldn't do so without spending caps. And West Virginia Sen. Joe Manchin, a Democrat, says he'll buck his party and vote against raising the debt ceiling.
