If it was fake, why the $130k payment from Trump's lawyer? Why the $150k from Trump's buddy at the National Inquirer, David Pecker, to not run her story? It is not as if it is unlikely that he would cheat on his current wife, having cheated on his two previous wives already and spoken about his philandering on the Billy Bush tape.
Trump has managed to get one major tax bill passed, a bill that should have been as easy as pie for a Republican with the House and Senate majority and the no filibuster rules somehow in place for a bill that will cause a major budget deficit.
How is that winning a lot? He was literally the least successful president in his first year in terms of winning legislation, and by far the least successful with his party controlling both Houses. His popularity is in the tank despite the strong economy Obama bequeathed him.
