Was Trump's entire presidency a disgrace or was it just the last 6 months before he left?

He was in violation of the emoluments clause on day one. His dog and pony show with stacks of empty manila folders showed that he had no intention of placing a barrier between his business interests and the presidency as did every president prior. If you cannot reasonably extricate yourself from businesses that stand to profit from the presidency, you have no business running for president.

Politically, It's not different from Obama's or Bush's

The same wars rage on, the same oil companies doing well, same prison problem, same guns and mass shooting.. 

Saying it's not the same is normal.

The orange shitstain entire life was a disgrace, probably from conception.

It was from day 1.

Of course because it started in controversy by way of Comey's termination!

According to Comey he was fired for not swearing loyalty to Trump by 'letting the Flynn thing go'!

He was a disgrace and an embarrassment from the beginning of his campaign and still continuing.  It's just not as bad right now because he left office and Twitter fired him.

President Trump was a top 3 President of all time. We had unrivaled prosperity, safety, and security. 

There were disgraceful aspects during the entire thing. Just a lot more during the last year.
