I have no faith in the average Republican voter. If the economy crashes they will blame Democrats and illegal immigrants.
However, just as an example, taking the truth of the '08 crash is a number of things. Repealing Glass-Steagall. Bond rating agencies rating garbage bonds at a AAA rating. Among other things. The '08 crash was not a partisan effort, and in my opinion, neither will a future crash. Although, if there is a crash, and I was the Democrats, I would bash the Republicans over the head, with their decision to repeal Dodd/Frank and tie them to all financial fallout. Even if it's not completely true. If the truth mattered a little bit pre-Trump, post-Trump the truth is like a rainbow unicorn, often whispered of, rarely seen. America needs a complete reset, no one tells the truth anymore, and everyone believes whatever explanation fits their narrative that Republicans are competent and right wing economics is smart.
