The basic debate here is pragmatism versus idealism. I'm of the latter. I'm more than willing to accept some short-term losses if the probability of long-term gains exists. In my opinion, they do.
And in my book, voting against the Constitution on a regular basis makes for an unacceptable candidate. Can I live with some things? Yes. But I have drawn a certain line and am not willing to cross it. Others have as well, though it's considerably to the left of where I stand. Those are in the pragmatist camp.
The pragmatists call the idealists "stupid" for not being willing to settle for what they can get.
The idealists think the pragmatists are a bunch of "sellouts".
Each of us needs to be right in our own mind.
I'm a pragmatic idealist. We cannot outlaw abortion except in cases where the mother's life is in danger right away, but we CAN start working at the edges, and building the consensus to reach that point now.
Why not work the edges? What is wrong with getting small chunks?
