The Republican Senators were in a no-win situation (or maybe I should say “no-gain”). Had they voted to open up the Senate hearing, they would not have gained any more votes for doing so. As well, they would have suffered a loss of support within the R party for not following the directive of the boss.
And by staying with the boss, they are guaranteed a 40% voter approval.
Clearly, the Republican senators could not vote their conscience or constituent desires. Their primary loyalty is to their Party, not the country or its people.
I should say that the same applies to the D party as well. Their primary loyalty is to their party.
A lot depends on the 125m Americans who normally do not vote. If just 2m or 3m can be convinced to make a trip to the voting stations and cast a D vote, it will be a D landslide. But is it prudent to leave this change to be managed by the D’s?
This whole impeachment process suggests it is time to look at an alternative to our current version of democracy.
