If anything Michigan probably ends up being to Trump what Indiana was to Obama.
Iowa could be as well.
No, it couldn’t.
The thing that annoys me about the IN 2008 comparison, is that it ignores the fact that both IN and MI are states that are trending away from the Democratic party. I could see MI being a tilt D state in the 2020s, but it wouldn't make any sense for it to be a fluke. It will continue to be competitive for the same reasons that IN is no longer competitive.
Sorry if you are annoyed, but what a lot of people do not get is that for every rural voter Republicans gain they lose one or more voters in more in urbanized areas. Kent County was a hardcore Republican county that bolstered Republican statewide margins, but in 2018 3 out of 4 statewide Democrats carried it. Democrats picked up 2 House seats. Parts of the state are trending right, but the more populated portions are trending left. But I'm not going to argue about it.
