Good article but I think you are wrong here. The small issues they disagree on are litmus issues for many people and the party members are expected to walk in lock step on them to maintain the divide. There are just enough of them that if one isn’t a big deal to you another will be. Abortion is one, but it doesn’t affect my vote. Gun control is another, it does affect my vote.
Yes, it is about more or less control freak government. I’m a small l libertarian but the Libertarian Party doesn’t seem to be able to get it’s shit together because it goes to such extremes on ideological purity.
I write in a lot of “no acceptable candidate” protest votes.
