But... it's bothersome that it just so happens this always leads to a certain style of "moderate" candidate.
Like... have you actually looked at crow's policy stances and whatnot? Dude doesn't exactly seem moderate in what he's saying he's after. He's arguably more center left than tillemann by stint of not endorsing specific propositions, not so much because of notable political lean. Still seems to support the same general goals (healthcare being an example, having not come out for specifically single payer or med-whatever for all, but still being explicitly pro-universal care and calling for a public option) and is, as near as a look can tell, solidly left on basically everything.
Closest thing to an argument on that front has been some of the guy's work history, near as I can tell, much of which seems to have some fairly mitigating circumstances (law work in general, being a junior whatsit when most of the questionable stuff was done, etc.).
