The worst allegation in Comey's own words is that Trump "hoped" Comey could get past the Flynn investigation because he knew that it was hogwash (not obstruction).
And even then, you are taking the word of a guy who has been caught lying under oath several times as well as the fact that he is a disgruntled employee with a grudge.
Comey is also under oath saying that Trump did not impede his investigation. So are the other Obama appointees at the IC agencies. Further, he is required by law to bring forward any instance where he feels inappropriate influence is being exerted on him on an investigation, and he never did so. Ergo, there was no untoward influence.
Also, Comey had multiple good reasons to be fired, and his leaking afterward confirms that it was a solid decision to do so. I would have fired the guy, and you would have too. You just can't see that because your TDS fever is raging too high right now.
Case closed.
