They have really fed your insanity.
Trump will win the travel ban case as soon as the case isn't heard in front of a cherry-picked court, he will have placed a conservative on the SCOTUS within a month or so, and he will eventually get a rescue to the Unaffordable Care Act passed (any political loss from this week is Paul Ryan's far more than Trump's.
We all know Obama surveilled Trump's campaign - it's evidenced even by the leaks on Flynn. You can call it whatever you like, but he was listening - and word got back to Hillary who tweeted about it on Oct 30th or so 2016. I do not think Obama is dumb enough not to have his minions do the task however, so i expect no smoking gun.
We also all assumed that the Loretta Lynch led DOJ would have issued an investigation into a Trump/Russia link since she is a political animal.
And Comey is Comey - he just likes jamming people.
So no, I don't think Trump has lost too much credibility. Of course, i don't watch Lawrence O'Donnell either.
