I'll tell you, it was a stunning thing for a lot of people who think Rubio is too young, too inexperienced.
It was a massive, massive statement and massive move for Rubio this week, and he's not alone. That's not the only thing that Rubio has done that has begun to put some distance between himself and others in the field. Now, it's still early, and it is why there aren't really any momentous things happening right now.
Marco Rubio Lights It Up
May 14, 2015
The Times’ Nate Cohn is a Rubio bear, calling him “talented but out of position”, whereas Harry Enten of FiveThirtyEight is bullish, anointing Mr Rubio as the “first real contender” in the GOP field...
Both forecasters recognise Mr Rubio’s many strengths. He is the party’s youngest and most telegenic candidate, and its best communicator. He has repeatedly exceeded expectations, securing offices no one thought he could win. His working-class upbringing with Cuban parents could endear him to Hispanic voters, and make it hard for Democrats to paint him as a pawn of the rich, as they did with Mitt Romney in 2012. He represents the country’s most populous swing state. He ran with Tea Party support in 2010, and his positions on fiscal and foreign policy are squarely aligned with his party's.
