if the money isn't close b/w Iowa and Notre Dame....I'd heavily lean toward Iowa
Why would you lean toward Iowa, if you don't mind my asking? And the money is weird, because ND offered me more but I pay instate at Iowa, so I've got $22,500/yr at ND and full tuition at Iowa.
I agree that Iowa is the heavy favorite with the money issue. If I had your option between Iowa and ND, I would pick Iowa. I think that the rankings will NOT matter (although Iowa is slightly higher).In addition, the fact you know Iowa so well is to your favor. Iowa places well in Chicago, St. Louis and any other major Midwest city. Iowa is a little older and typically has a larger class. This translates into a larger alumni network across the country. That network is important for finding the "right" fit for you. I am not sure what type of law you are interested in but Iowa has a great program for all different types and the faculty are among the best (not to say ND doesn't have some good ones). Also, the fact that you will have no financial problems coming out of Iowa is great.
Notre Dame is a good school, it is very conservative and traditional. I am not sure how your politics will play into this issue. It is just something to think about.
Iowa sports have been much more fun to watch lately. ND football has not been great at all!
