The first Trump impeachment was sparked because Trump was starting to look into Ukraine. Remember Alexander Vindman?
Ukraine (excepting open checkbooks, men, and materials) is a subject 'not to be discussed', like the 'suddenly' fellow that seems to be killing off athletes and younger people.
Comey refused to go after Hillary for a server she kept in a bathroom. His successor Wray shows up at the WEF practically bragging.
The dots, at least to me, don't seem particularly hard to connect.
The only reason 'no regrets' Biden might have is that some faction in the Federal apparatus is prepared to throw him under the bus. Yes, I believe there are factions fighting like hungry dogs over who gets to feed on what is becoming the carcass of the American experiment. And at least some of those factions are engaged in treason.
The American Experiment depended on several key pillars to enable it to have any chance of long term success: a well informed and engaged populace, some semblance of moral standards, an honest press, protected rights and liberties, an equitable legal system, and accountability in society.
Those pillars have all eroded away, undermining the Great American Experiment in self-governance.
We are becoming more like Rome everyday.
How else is a crooked politician supposed to get paid?
