Imagine someone eating coffee grounds and washing it down with Jolt Cola.
That person would talk slower than Rubio. And sweat less.
He is acting like someone who has ingested SPEED!
rubio snorts cocaine just to relax.
And the way he keeps licking his lips, at least he did previously. It might be reaction to a prescription drug. Also, I have observed similar reactions to certain illegal drug. No, I am not accusing him of it.
