Anybody that ever took an interest in past presidential elections know its a tough campaign to win.
The knowledge behind winning is well known and pretty much stays the same.
You have to campaign and your VP pick is very important.
Beating an incumbent President with a positive attitude,a good economic message and a great foreign policy is an impossibility.
Especially when that incumbent President increases his vote total, a rare occurrence, Obama got less the second time.
Somehow Senile Joe campaigning from his basement got more votes than Obama did the first time.
