Obama and the Deep State spying on the Trump campaign
heinous as it was (probably not but I'm throwing you a bone), has very little or nothing to do with Trump's low popularity or his failure to accomplish much.
But he is rapidly accomplishing the most important parts of The Blob's* agenda of removing expertise from government and erecting a judicial wall to protect them for a few decades.
*more or less The Deep State in the Trump Era. Defense, Gunz, fossil fuels, finance being very well served here.
