Voting is about choosing good candidates well before it gets pared down to 2 options. It’s about choosing a good local government, choosing good representatives, choosing good senators. If the only thing you care about is the President, then you’ll never have a good pool of options from which the parties will pick a presidential candidate. They’re not on our side - it’s our job to force their hand with a deck stacked with good candidates. But only the people who pay attention to politics well before election year get to have a say in stuff like that.
