There was nothing interesting about the Iowa caucuses. Mitt Romney got more or less his expected 25%. Rick Santorum was the not-Romney candidate of the moment, and got about the same vote. Ron Paul got the votes he was expected to get, high for a non-mainstream candidate, but not enough to make him mainstream. If the vote had been held 10 days earlier, the not-Romney vote would have gone to Newt Gingrich. If it had been 20 days earlier, the non-Romney vote would have gone to Herman Cain.
Mitt was smart to move the non-Mitt vote to Santorum instead of Gingrich, because Santorum will be a weaker challenger. But none of the non-Mitts really had much support of their own.
What a waste of time, energy, and money! And how discouraging to think that this is how Americans elect a President.
