Lanny Davis: I agree with Trump that 'narcissist' Comey should have been fired

"I think he should have been fired because he thinks he gets to choose which rules to follow and which rules not," Davis said on "Fox & Friends."

"Why? Because is he a narcissist who gets to decide who is right and who is wrong rather than following the rules," he added.

Davis, a friend of Hillary Clinton who became special counsel to former President Bill ClintonWilliam (Bill) Jefferson ClintonKentucky candidate takes heat for tweeting he'd like to use congressman for target practice Will Sessions let other 'McCabes' off the hook or restore faith in justice? Progressive group launches anti-Trump 'We the Constitution' campaign MORE when he was in office, also used slides to argue that Hillary Clinton would have beaten President Trump if Comey had not decided to reopen the investigation into Clinton's handling of classified information while secretary of State. Davis — who is also a columnist for The Hill — makes the argument in his new book, "The Unmasking of the President 2016."

“On the morning of Oct. 28, [2016], Hillary Clinton is ahead in RealClearPolitics average of polls by 5.9 percent. Which, by the way, called the national election on Election Day within 1.2 percent, which is pretty accurate."

"Slide Two shows the affect in three key battleground states, Pennsylvania, Michigan and Wisconsin, where she was up 5 to 6 points on the morning of Oct. 28," he continued.

"Within 11 days she plunges; it looks like the stock market last week, and it’s a direct effect of the Comey letter [to reopen the investigation around mishandling of classified emails].

"And the final slide is the electoral map on the morning of Oct. 28, 2016, and that is the way it would have looked but for James Comey," he continued.

"Remember, James Comey doesn’t have to follow the rules. He gets to decide what’s right. His new book is talking about a higher loyalty. Do you know what that loyalty is? To himself, not to the policies of the Justice Department.”

Trump would lose the popular vote but win the Electoral College comfortably by a 304-232 margin after narrowly winning "blue wall" states that usually go Democratic in presidential elections, including Wisconsin, Pennsylvania and Michigan.
