He sounds so young and scripted and awkward. I thought this guy was supposed to be a good, inspiring, passionate speaker? He sounds like a GPS.
Scripted and awkward is one of Rubio's two common speaking modes. The other is nervous and awkward.
He can sometimes fake charisma. I'd guess he does so via extensive rehearsal.
As I've said again and again, I think current popular picture of Rubio as "the" establishment candidate is wrong. He's a flavour of the month, and his time will soon be up. The longerhe stumbles onward without crashing, the worse the impact of his fall will be for the Republican establishment.
