I will be going on leave soon - today is my last column for a while because of the holiday schedule - to write what I believe to be the most important thing that I've ever written. No, it's not about US President Donald Trump, just in case you were wondering.

But since I have written almost exclusively about Trump for more than two years, please allow me this parting assessment: it is so much worse than I thought.

My original objections to Trump, the things that pushed me into the Resistance, were his immorality, dishonesty, fraudulence and graft. I freely admit now that I was seeing only the pointy edge of an enormous machine. I had no idea how immoral Trump actually is.

The same month that Trump pulled the outrageous stunt of inviting women who had accused Bill Clinton of inappropriate sexual behaviour to his debate with Hillary Clinton, his personal lawyer, Michael Cohen, apparently under his instructions, facilitated a $US130,000 payment to porn star Stormy Daniels to prevent her from telling America that she had a sexual encounter with Trump, who was married with a small child.
