@hightor,
I see two encouraging signs in all this. First, though the political news media is ill-equipped to deal with a figure like Trump, they are continuing to take him to task for all the things he's guilty of to a degree I've not seen before. The other day, snood made the understandable complaint that the recent NYT interview with Trump was merely doing stenography. I think that's accurate, but this is not always bad. The reason lawyers commonly manage their client's speech is because they recognize the dangers inherent in allowing that client to "hang himself". In any case, as I've said before, I think Jay Rosen has this Trump/media dilemma described better than anyone else.
Second, even given the right wing media's very real influence on US politics, Trump's popularity ratings continue to plummet. And along with that, there appears to be a strongly resurgent seriousness and activism on the left. With the two party system, I don't know how the US ever breaks away from the binary formulations but even within that constraint, the GOP could very well face a real ****-kicking next November.
And yeah, Flake proved himself unworthy of trust. But he wasn't the only one in the Senate to do so.
