One thing about being a political junkie is you become acquainted with the art of the possible, rather than the art of what should be. I roll my eyes a lot at, for example, people who think my local transit authority should just triple service levels, or have buses that fly, or whatever. But the point is often those people are right! That should be what happens! I roll my eyes because I know all too well why those things don't happen, and those people probably don't, but that doesn't mean they're wrong.
It's too easy to get trapped into the constraints of what can be. We shouldn't forget what should be.
