How popular are progressive policies, really?

There are several reasons to think polls might overestimate support for left-leaning opinions

Happy Saturday evening, all. I wanted to write this post sooner, but am about 10,000 words away from wrapping up my book and am plowing full-speed ahead to finish by my deadline on February 28th. At any rate, the added time has probably improved this post, so you're welcome.

I have written before about whether we can trust public opinion polls of policy preferences — called "issue polls" in the survey industry — given that pre-election polls appear to be demonstrably and continuously biased against Republicans, at least on average (IE not in all geographies or in all races or in all years — I feel like I have to say that to avoid emails where people say "umm, actually, the polls in Georgia were pretty good this year!").
