Agree, disagree, disparage, whatever, here is my reply.
Watergate was a bungled, ill-advised, illegal break-in and burglary attempt that was made a scandal as a result of the cover-up. Hence the phrase, "it's not the crime, it's the cover-up." As a result of the cover-up, Nixon lost support and was forced from office. And some went to prison.
The scandal of Spygate is not about the cover-up. It's about the crime. It's about unelected government bureaucrats conspiring to take a series of actions with the intent to first influence, and then overturn the result of an election. It's about those bureaucrats deciding to hell with the will of the American people. That's dangerous.
I am totally uncool with the idea that rogue individuals in various government agencies, the FBI, the CIA, the NSA, took it upon themselves to game the system and to even think about thwarting the will of the electorate. That's what makes this bigger than Watergate. Way bigger. At least seven times bigger. It has zero to do with anything that may or may not happen to 0bama. You seem to be fixated on that.
Likewise, I am totally uncool with the role Hillary and the DNC played in terms of funding the trumped up dossier which was then used to get the FISA warrant which led to spying on the campaign and American citizens. In fact, that is where collusion with foreign agents took place (Steele among others) and that makes it bigger than anything Watergate has to offer.
With respect to your point that repercussions are unlikely because those I named will claim justification in going after Trump because they suspected treason was in play: How ironic in that whereas Trump, according to Mueller, did not collude with foreign agents, these folks certainly did. Does that mean they committed treason? Arguably yes. Nobody associated with Watergate committed treason.
