"I believe that IA also went for Dukakis, didn't it?"
Yes, as did Wisconsin. But I didn't include them on the list because it wasn't totally due to union Democrats, as was proven in 2000 and 2004 when Gore and Kerry each got between 48%-50% in each state; a surprisingly high number of Iowans and Wisconsinites are social liberals, although both states are still for the most part pro-life.
