As soon as you mention Hitler, you lose. All the hand wringing in the world will not make this like Hitler, Watergate, the e-mail scandal, the IRS scandal or any of the other high-level scandals in history.
It is not despotic behavior. Comey was incompetent. All the investigations that are ongoing will continue to be ongoing. The head of the FBI does not run the country, and he knows nothign more than the department as a whole already knows (except for maybe what deals he made with Lynch about the Hillary investigation). The fact that you think an incompetent staffer is untouchable is pretty banana republic thinking.
The sheeple were the ones lining up behind Obama, including the media. They also lined up behind Hillary. Your perspective is hazy.
Thus far, there has been no credible evidence of Trump colluding with the Russians, and I believe that whole issue was born of "lies and misinformation" spread through "propaganda channels", and this plan was hatched before Trump took office in order to hamper his presidency. If he was indeed colluding with the Russians, he will pay the price for that, and it will be discovered by the many investigations that are ongoing. I hope they start investigating Comey and the previous administration....maybe a special prosecutor is appropriate there.
