So you honestly believe its the Repoblicans fault?
No, not sure how you got that specifically. It's the voters fault and the politicians fault. Voters for remaining ignorant and easily manipulated, and politicians for taking advantage of it. My anecdote is all conservatives I know are single issue voters. Maybe they don't about the 2A, but they care about being probirth or vice versa.
It took us 50 years to get to this point, but what we have is corporations and wealthy basically writing legislation for themselves. Are the R's complicit in this? You bet. Are the D's? Much less so, because as I said....and much more diverse makeup.
R's policy's are not popular with the general public. But as I said, enjoy an easy voting group to pander to. Trump had to expand that to white nationalists and people afraid of losing their place in line to win, fueled by social media propaganda and blatant lies.
D's policy's are more so. While Biden is a centrist, he knows what the D's in Congress are migrating towards.
If you don't listen to Noam Chomsky, I suggest you give him a listen. He certainly struck a chord with me. He has a video called Requiem for the American Dream that is dead on.
