I'm seeing pro-Trump Facebook posts from people back home I would never have expected to vote Republican. Trump certainly has made inroads with traditionally democratic blue collar whites in Ohio, but not nearly as much in Wisconsin (yet the media keeps citing it as a state Trump is expected to do well in for some strange reason). In recent decades rural working class whites have mostly left the Democratic Party but their urban counterparts had not prior to this year. You can look through the DRA map of Ohio and see across the state red townships and blue cities or even blue villages. It will be interesting to see what the map will look like this year, but it seems, anecdotally at least, that the white poor urban cores are moving toward Trump. What remains to be seen is whether this is a small trend or a dam bursting.
I don't quite understand why Iowa is so pro-Trump, but perhaps it is similar to the effect in Ohio since Iowa also has a lot of smaller white manufacturing towns without as many major cities as Ohio.
Very interesting.
