I've updated the "Iowa Blogroll" in the right sidebar and have included a lot more of the best state blogs (including a few lefty sites for fun). I also have a section linking to some blogs or column features of major Iowa news outlets where lots of comments are often generated.
Also, I feel a little like a Ronulan (my favorite nickname for Ron Paul supporters . . . and no, I'm not a total Star Trek nerd) doing this, but there are some online polls at a few Iowa based blogsites that Romney could win with a little boost.
