Republicans won six Democratic-held Iowa Senate districts in 2016. All of them were among the eighteen Iowa Senate districts where voters had favored President Barack Obama in 2012 but Donald Trump four years later.*
Some of the largest swings toward Trump occurred in northeast Iowa. Parts of four counties make up Senate district 32, where Democrat Pam Egli recently announced that she will challenge first term State Senator Craig Johnson.
While this race does not currently appear to be among the best 2020 pickup opportunities for Democrats in the upper chamber, it could become competitive. Either way, state legislative elections in this part of Iowa will be important to watch for signs of whether Republicans are able consolidate their 2016 gains.
