Yes, it is going to take longer if it happens. In this situation, you are right, the impeachment show is all that is left. Trump and his remaining stooges will continue their destruction while smashing into things and each other. Trump will announce crimes and then commit them in juvenile defiance.
I was hoping for a Republican break but there is no one left. Nunes and crowd were fully into the Ukraine play so are incriminated badly and would end up in prison.
This was never going to end well for the US but the destruction will, at some point, either break the country in pieces or reach some threshold of unimaginable disgust and explode or collapse into hopeless despair when the election fails.
Russia is the wildcard. Putin is prompting Trump openly now and Moscow Mitch seems firmly in Putin’s pocket. The GRU has everything operating and are now microtargeting exurb old folks with account confiscation to sell very high priced gold coins and drive fear.
This is the same electoral college scam that worked in 2016. It will come down to controlling some 10k low information voters and Trump will be president for life.
Moscow Mitch has blocked all efforts to protect the election so there is really nothing that can be done.
