I'll make a prediction: the personal, shake your hand and actually talk to you politics of Iowa and New Hampshire is over. In those small states, someone can spend time instead of money, and pull off an upset. Huckabee being a case in point in Iowa.
From now on, money's going to rule, and only well financed candidates will have a chance. Florida is the next primary, in a few days, and then comes the February primaries with 23 states holding primaries at the same time. No way a candidate can spend time instead of money in 23 states at once. Big bucks will rule in February. I've heard the figure that 3 million will have to be spent for a candidate to win in New York, and 4 million in California.
That narrows the field a lot, on the Republican side. Romney is the only candidate with enough money, right now. McCain may be able to raise enough to compete. Unless Guiliani pulls off a big win in Florida, he's done- he won't be able to raise enough money. Same for Huckabee.
