From what I have been reading about Iowa, I don’t think they know what they want, and they are pretty irrelevant anyway.;
They are making such a mess of this they should have their caucus last instead of first and save themselves the embarrassment.
Actually, the numbers that will be reported from the Iowa caucuses will be from a non-binding straw vote. No national delegates to the GOP convention will be selected by the caucuses either.
Caucuses select delegates to the later 99 county conventions, and to the state convention, and the caucuses begin the work of compiling a party platform.
