I have no idea what’s in Trump’s tax returns, but I think Democrats have this tendency to look for silver bullets to defeat Trump that come from outside the normal flow of politics, whether it’s hoping Mueller finds something or releasing the tax returns.
That just seems stupid — even if either or both turn something up. Every election Trump has been involved in has been pretty normal in terms of the results and what we’d expect based on the fundamentals. I think they need a “normal” plan to beat Trump, even if they also have more moonshot hopes.
