Manchin didn't want a $15 raise. Democrats couldn't add it to the covid relief bill since it had nothing to do with budgets, so the next option would have been a separate vote. Again, I have no idea why progressives are obsessed with purity tests they know will fail to achieve anything. It's reminiscent of how the Tea Party operated. It failed for them and it'll fail for progressives.
There weren't 60 votes for the $15 minimum wage. Now, there seems to be some bipartisan support for raising it to $11-12. We'll see what happens but once again I suspect we'll see another example of one group of people making possible change, working within the system...and another group whose entire focus is on performative actions that benefit no one sitting on their hands bytching.
Progressives don't understand power or leverage, and it kills them every time.
