Nixon won the 1972 election in a  landslide and the Watergate breaking didn't influence that election outcome. However, within 2 years he was forced to resign before he could be impeached. Why?  Because he and his close advisors lied about their involvement and  tried to cover it up.    That is the parallel with Trump and his advisors. They keep saying there was no involvement and then more information keeps coming out proving them wrong or that they lied about meetings actually taking place.  

It is no longer about the election results. It is about Trump and his advisors credibility and truthfulness.  Kushner did not declare his involvement in this meeting on his security clearance form.  Forgetful or convenient?These are the mistakes that are doing in the Trump administration.  The media did not make them but they are rightfully reporting them.
