Hello Gonzomin,
Trump knows the truth. That is why he refuses to testify under oath and prohibited anyone he ever met from answering subpoenas to testify. These are not the actions of an innocent man. I suspect Trump knows he is fading mentally. That is why no press conferences either. He should not run again, but he needs to get help from the statute of limitations. Many of his crimes will drop off the calendar. He does not want to spend his last years in courts or in jail.
Donald Trump has created his own worst nightmare. He never should have gone through with becoming President. He really only ran for the free publicity to further his brand name, but that has totally backfired. He had it made with huge brand name recognition. He effectively exploited the principle that even bad PR is good because after a few years people forget the details of a story but remember the name. And that was his goal. Name recognition. But now he has OD'd on name recognition and people are becoming all too aware of the details of his dirty life as a conman.
He had this 'great' idea to get the free publicity of running for President and he figured no way he would ever get elected, but something unexpected happened during the campaign. He attracted way more support than he ever anticipated and it went to his head. And some very powerful players latched onto his campaign which they saw as a way to further their anarchistic goals. Putin, Bannon, Roger Stone, etc. It went to his head. He was unable to hold just the few original rallies and experience thousands of admirers without having his ego squash his original plan.
We know Trump never really wanted the job because he offered John Kasich 'the most powerful Vice Presidency ever.' Apparently he courted the notion of winning the election and then letting Kasich run the office as he assumed a 'shadow presidency.' The Obama team said they never say anything like it when the Trump people showed up to learn how to take over the WH. The Trump people had zero idea of what the job entailed, who they would need, the tasks which would have to be done, the jobs which would need to be filled.
Trump's dream world has not turned out anything like he hoped because he was completely unrealistic and had no idea what he was doing when his ego decided to go through with becoming President. He completely failed to realize that, while he was able to fly under the radar as a private citizen, that all changed when he took the oath. Now he has a tough time hiding all his dirty details and keeping all the skeletons in his closet. I am frankly surprised he has lasted this long. He himself thought he was toast as soon as Mueller got appointed. With each scare he survives, he becomes further emboldened.
When Senate Republicans let him off the hook for this impeachment, he will then believe he has absolute power.
And we KNOW where that leads.
He is going down, one way or another.
Something to note:
There is no double indemnity on impeachment. It is not a criminal trial. It is a job review. He can be impeached again and again for the same things. All the House needs is new evidence and they can bring it all right back up again. This exercise may simply be one of giving the President enough rope to hang himself.
