If it turns out for example that the presidency had nothing to do with any of that, if it turns out that it was entirely irrelevant and he is firing Comey for political reasons it pretty much dies on the vine, but if it goes further than that to show that he is trying to protect either himself, or some other member of his team from the disclosure of an event that would be criminal or an huge embarrassment and he goes through illegal acts that would prevent the disclosure, then he is going to get himself into trouble.

There is a whole lot of downside risk. That's the lessons of 1973 and 1974 and 1975 -- these things evolve a life of their own and your conduct really is like anger and revenge -- served hot they are very dangerous, served cold they are different.
