I am not all that inspired to listen to some dumb speech that Rubio had written for him by some agent of the Koch Brothers or the Fanjul Sugar Lobby.
Rubio is an empty suit, for rent to anyone who helps him further his ambition.
Rubio has done nothing truly useful for anyone who has voted for him during his entire life. Every job he has been elected to has been treated as a mere stepping stone to the next. The guy is a shameless opportunist.
