Probably the same reason why people get mad people focus all their energy on the people they have more in common with rather than the people who hate them and are spending their time and energy on how to make their lives worse.
Honestly it wouldn’t be a big deal if they
ever brought up the GQP. But they don’t, and when pressed the response is “well of course they are bad”. Uh then at minimum have the same energy for them too.
Multiple things can be true at once. The current dem leadership can be trash, but also preferable to the people actively working to take us back to the 1700s.
People can be apathetic if they want. Just don’t complain when other people arent and proceed to vote in people that will make your life miserable for the next few decades.
