The findings in this article, where they went back after three years and found no change in a group of two dozen or so people, strikes me as having a high likelihood of being repeated in more places than not. In my travels, I've not seen any indications there's a ground swell of movement away from Trump on the part of those who supported him the first time around. I agree with this article that, if anything, support for Trump in those five or six key states is more likely than not to be higher than in 2016.
The Democrats and media refused to acknowledge why they lost in 2016 and it's looking like its too late now even if they did have an honest come to Jesus conversion.
I'm not committing to this thought but I'm wondering if the ONLY Democrat who stands at least a small chance is Amy Klobuchar. She's the least crazy one in a room full of crazies. She's the only one who scares me in a one on one.
