In essence I think you are right, but I think there’s more to it. Trump got under the skin of a segment of the population (mostly liberals who have never been outside the bubbles of government, academia, and media) so much that they literally went insane (more so than normal). You had fake hate crimes, more violence, pussy hats, news anchors with decades of experience crying. This mass insanity afflicted the Obama administration and DNC too. Just like the IC with Bush and WMDs I think they really thought 100% they had something with this Russia collusion. I really think they thought he would be gone by now.
