I think Angry Joe Biden will come out Guns Blazing. He's a loud speaker, and he will win the Headlines with his attacks on Romney. He'll attack Romney for being rich and out of touch. Biden has no qualms about using the 47% line. He'll attack Bain.
But the worse thing Biden can do is have a senior senile moment, and say something completely Crazy or Incorrect, that can also doom the Obama campaign. But basically, Biden is practicing his Zingers like "verb, noun, and 9-11" and his bad or awful jokes.
All Ryan needs to do is focus on being calm, smart, and a supporter of the unemployed Middle Class.
As long as Ryan doesn't say anything about cutting Medicare, Social Security, or anything in the Ryan budget and just run away from the Ryan budget, then he will have done enough to keep the supporters for Romney.
All Ryan needs to do is present himself as a working-class Catholic guy from the midwest.
So all he has to do is abandon all of his life's work and not be Paul Ryan and he'll win?
