Trump plays the same hand every time. If he's accused of something, he tries to turn it onto his rivals. Collusion in Russian wiretapping.... Accuse Obama of wiretapping him. 
Sniffing like a true coke addict during the debates... Challenge Hillary to a drug test. 
Provably lying over 70 percent of the time. Accuse legitimate news agencies of publishing fake news. It's a pattern worth noting. 
This time though, he can't bluff his way out.
