After keeping his head down for a couple of months to learn the rigors of Washington, Florida U.S. Senator Marco Rubio has opted to break out into the national spotlight this week. In addition to appearances Tuesday night on Fox News Hannity and ABC News's Nightline programs, the freshman Republican penned an op-ed in Wednesday's Wall Street Journal entitled Why I Won't Vote To Raise the Debt Limit, which will be an issue for every man and woman in Congress to contend with when it is expected to come up for a vote in another month or so.

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.

But more importantly, Rubio is now finally speaking his mind on what's happening with Libya, where 13 days ago he was outspoken in blasting President Obama for not doing anything about the situation in that country. Refreshingly, and unlike Newt Gingrich, Rubio is remaining consistent, saying he's pleased the U.S. is involved in the effort and is not bashing Obama for somehow being "too late" in getting involved, even though the White House has been criticized for going to war too quickly, less than 48 hours after the United Nations Security Council approved a no-fly zone in the region.

Rubio spoke today about Libya (and other things) while speaking on ABC's Good Morning America Wednesday morning with George Stephanopoulos:
