WASHINGTON -- A young, fresh-faced senator full of optimism for what America can be is once again running for president. No, it's not 2008's Barack Obama, who instilled hope in a war-weary and financially rattled nation. It's Sen. Marco Rubio (R-Fla.), a 43-year-old son of Cuban immigrants who is touting his compelling family story as an example of why, to borrow a familiar phrase, "you can make it here in America if you're willing to try."
But as he mounts his bid for the White House in 2016, Rubio is facing the same questions then-Sen. Obama faced in 2008. Is he too inexperienced -- he's only been in Washington since January 2011 -- to take on the challenges of the highest office in the land? Does he have enough executive experience, especially compared to the number of Republican governors running for office?
Going into his campaign, Rubio is positioning himself much like Obama -- who eventually successfully parried concerns made by then-Sen. Hillary Clinton (D) -- did so many years ago: as the agent of change and the voice of a new generation. In fact, there's some striking rhetorical similarities between the two men. See if you can spot the differences in the quiz below.
