I gave my impression and it was an honest one. Clearly, you disagree.

Are Mueller and Comey trying to bring Trump down or are they trying to get at the truth, no matter where it leads? I hope it's the latter. And if that has the ultimate result of ending this presidency, that's fine with me.

As for your list of viable candidates, it depends on what you mean by viable. If you mean any of them can win the Democratic nomination, perhaps. If you think it means any of them can win the presidency, I wouldn't bet on it. Biden, perhaps, but I'm not sure he has the fire in the belly anymore.
