They didn’t ignore this reality. They tried to move to the right, and woo right wing voters, trotting out Liz Cheney, acting and talking like Republicans. And it accomplished nothing: R’s voted with their party. It was a total failure.
Liz Cheney was a great get on their part. It’s the rest of it that was the issue. They should have gone hard left and still had Liz up there, for the full-spectrum effect. “Even this crazy conservative woman thinks Kamala’s great” but then everything else: left left left.
They’re both working for capitalists. Democrats bank on getting the support of capitalists that have morals. Unfortunately most capitalists, and the wealthiest capitalists, don’t. When both parties appeal to the same group but one gives them more of what they want unsurprisingly that’s the one that wins.
The working class is invisible because the working class is not organized.
