Aside from the blatant inaccuracies about what Donal Trump inherited, I would have agreed with you until I witnessed the last year or so. He has lied, outrageously on issues large and small, that would have destroyed past presidential candidates and political leaders.
The Tea Party supporters and the Republican party began a process and followed it about destroying the reputation of their opponents (something I submit that Harper did on a lesser scale) rather than their politics.
The big danger in this is not that that one person wins or loses a political race - it is that respect for an entire institution is destroyed and it sets a new base line. The new line is that any untruth or lie is completely legitimate.
Trump and his biggest supporters are destroying the integrity of every organization they are in.
