Is the same reason why the MSM does not cover the election fraud story, and why the New York Times won't write about it:
"Go to any elite university and you are usually speaking to very disciplined people, people who have been selected for obedience. And that makes sense. If you've resisted the temptation to tell the teacher, "You're an asshole," which maybe he or she is, and if you don't say, "That's idiotic," when you get a stupid assignment, you will gradually pass through the required filters. You will end up at a good college and eventually with a good job." -Noam Chomsky
The United States Senate is the most elite club on the planet. Democrat or Republican, neocon or neo-liberal, these are very cautious, career-oriented individuals who have been rigorously selected for obedience to the official story.
No, Virginia, no Senator will stand up on January 6. America will continue its decline. You can call it cowardice, but that is not really what it is. It is a systemic problem. These Senators do not know how to behave any other way.
