Since Cyndi Hanson is running in the republican primary and Scholten is running against the primary winner in the general election. that isn’t a real thing.
But if you really only care about unseating steve king (certainly a laudable goal), the most likely way to do that would to be to get someone like Hanson running in the general election as an independent with Scholten bowing out. But I am all for anyone opposing steve king in any way.
I do get frustrated when liberals fight with each other over purity and turn a “safe” seat into a trumpist victory. But steve king is a popular incumbent in a conservative district. He is nearly “live boy / dead girl” safe. So I applaud anyone who opposes him from any party.
