If moderates ask progressives to “vote blue no matter who”

Worth saying that applies to the general only. I’m a progressive and I say: Vote progressive as far as you can. Always vote for the most progressive (or least regressive) candidate. In the general election, that’s gonna be blue over red. In the primary, that’s any progressive candidate. “Blue no matter who” is just expressing the pragmatic general rule of thumb. I haven’t seen any exceptions to that - I’ve never seen a Republican that wasn’t more regressive than an establishment Democrat option.
