I no longer believe that $$$$ alone is the determining factor. Yes, it helps...but to see it as the DETERMINING factor is to underestimate the American people. The “overly-exposed” Obama has made the same mistake.
Money is the main factor. You need money to run adds, money for polling, money for focus studies. You need money to reach the people, and to know HOW to reach them.
Cain as of yet, doesn’t have the war chest to run long term. One of the reasons Romney wants to accelerate the primaries is that it forces everyone to move on to the bigger states. Cain can run in Iowa and New Hampshire, they are small states. He doesn’t have the cash on had to sell adds to all of Florida.
