DENVER (CNN) - A glimpse of Joe Biden - who has been back in the spotlight for less than one week. He found out he was being tapped for the ticket on Thursday. The rest of the country found out on Saturday. Now it’s Monday night. It’s amazing how fast these things happen.
And by the way, our polling shows, when he was named, even though he’s run for president twice, most Americans don’t know who he is.
Obama may have wanted to choose Virginia Gov. Tim Kaine — who has joined him on the trail in the new battleground state of Virginia - but the sudden emergence of the crisis in Georgia, which coincided with his dip in the polls, may have convinced him that he needed someone of foreign policy stature.
