While I found Mr. Trump somewhat entertaining for a while, his little act last night clearly showed his lack of "Presidential" demeanor. You don't stand on a stage and call a fellow candidate a liar.
The GOP is going to lose this election if they don't start focusing their attack on the liar or the socialist. Our candidates should talk about what they will do in direct terms and facts and not what happened under George W or even Ronald Reagan. Shame on these guys.
As for the current POTUS and the appointment of a new judge to replace Justice Scalia. Mitch McConnell attacked the appointment minutes after the announcement of the death. Conversely Obama is already planning a replacement before the body is cold. Both sides in this issue show they don't give a damn about an individual life. They care about their political agendas.
The GOP will block any appointee nominated by Obama. The dems would do the same thing if the shoe was on the other foot.
