We'll see if this stuff works, but I'm quite skeptical. Trump tried a version of this to close out the 2018 campaign, and it didn't work. https://twitter.com/acosta/status/1284599642047512576 https://www.cnn.com/2020/07/18/politics/trump-law-and-order/index.html
We got a freaking pandemic going on. The idea that this election won't be a referendum on Trump's performance during that pandemic seems... not right. If things get better, you can see Trump becoming more competitive with Biden. Without that... I'm doubtful.
Most big things are connected with that pandemic... Economy, schools, etc... It all comes from that... To me, it seems so obvious... Maybe I'm wrong, but so far the polling looks like you'd expect given it all...
