John McCain Wednesday endorsed Florida Senator Marco Rubio to be the Republican nominee for Vice President this November.
This was in response to Jay Leno's question regarding the matter on NBC's Tonight Show (video follows with transcribed highlights and commentary):
McCain also mentioned New Jersey Governor Chris Christie as an option, "But I served with Marco Rubio. He's an amazing talent."
Then McCain joked, "Remember, the Vice President only has two duties. One, in the case of a tie vote in the Senate, he comes and breaks the tie."
"The other responsibility," McCain continued, "is to inquire daily as to the health of the President. So it's not really a demanding job."
That said, it's interesting to note McCain backed Charlie Crist over Rubio in Florida's senatorial primary in 2010.
