I kind of feel bad for Marco Rubio. Four years ago, he was definitely a thing. Nice guy, cute wife, lovely family, good backstory, conservative yet acceptably well-thought-out positions on key issues, and the kind of fighting spirit that made you think that he was uniquely qualified to lead the next generation of Republicans in Congress.
And then Ted Cruz got elected.
I'm not saying that one is particularly better than the other, but Marco Rubio has been overshadowed as of late by sparklier stars. Where he was once a hot commodity, he'snow been relegated to that speaking slot at CPAC that happens before everyone's morning coffee, and while reporters in the audience are still trying to piece together the night before. He's a good guy, and he'd be a great candidate for President - if we could turn back the clock and let him "do over" the last few years.
Regardless of time traveling ability, however, he's thrown his hat into the ring.
