. . . WHY are we letting them exist, much less "merge"???

Republicans no longer exist, at least not the way they want you to think they do. 

But if we're all aware of the complete scams of covid and global warming (that's been a scam since the 1970's) why do we let them continue?  Why do we pretend to be a 2 party nation when we know full well there is no such thing.

Oh, there are 2 named parties all right, but in thought, they are 1.  You don't have to go far to find the evidence either.  Register as an Independent.  Or just don't bother to vote because shams never get better, only worse, as you can see with your own eyes if you're looking.
