I'm aware of that, GM, and the thing is it is because of that you have to look a little closer at Obama's victory there. Biden, Dodd, Richardson, Kucinich and other campaigns that knew they may not get enough support gave instructions to their people to "join with" other candidates because at a caucus, as you pointed out, that's how it's done. The thinking is all (or most) of these other Democrats asked their people to join with Obama if they did not garner enough support. That may be why he won and why it may have been a lot closer in Iowa than most people think on the Democrat side.
