I found this while looking for info on the voting results (I couldn't find any yet), from a link on the Iowa GOP website.

This is the official liveblogger for the straw poll, with some short analysis of crowd reactions to speeches.  The thing that interested me the most is that there are so many Ron Paul supporters there.  The guy said that the person doing introductions was having a hard time because his supporters were "everywhere" and really loud.  The liveblogger said that Ron Paul got the biggest reaction of everyone except Romney, but it was just about as loud, and the only thing the crowd did not like was him saying "the national ID was is mistake".

Second, apparently the Huckabee guys showed up strong as well, and they were chanting "I like Mike" He did a lot of Clinton bashing, basically saying that good things can come from Arkansas as well.

Based on this, I stand by my earlier comments of a possible Ron Paul surge or even a Huckabee or Brownback one.  I think that the first two COULD compete with a democrat, but it wont matter.  I say this because Huckabee may be a wingnut and may not believe in evolution, but when he talks about why he doesn't sound crazy.  There is a rationale for him, and with evolution he brings in science and says basically "God started it, whether we evolved I don't know" And Ron Paul is more liberal (although more crazy, since he wants to get rid of I think 5 departments, the IRS, Social Security and some other things.)

I guess we will see over the next few days/weeks.
