It's hard to write a tell-all book when Trump is constantly telling on himself

Veteran journalist Bob Woodward's new book, "Rage," hasn't even been released yet and it's already causing quite a stir. In it, President Donald Trump acknowledged in early February that the novel coronavirus was airborne and deadlier than the flu, even though he continued to downplay the threat of the virus in public.

 This is hard to believe given that the President does little to evoke calm. Indeed, as the story broke, and Woodward released recordings of his conversations with Trump, the President continued to tweet about the alleged breakdown of law and order in the country, stoking fears of violence in response to largely peaceful protests.

 Fast forward to 2020 and things are vastly different. It is possible that Woodward's book won't do much to sway public opinion. The intense partisan polarization in the electorate means that there are fewer undecided voters who might be swayed either way by the revelations in Woodward's new book.
