Essentially the same question as I asked conservatives (and inspired by this essay): which policy options are simply off the table because they are perceived as too far to the left?
I guess I'll leave it to everyone to define for themselves what "off the table" means. I certainly wouldn't include anything that had serious support from Democrats in Congress. If this is a serious issue, it has to be, I'd say, not just about things that lose (such as card check, or the public option on health care), but about policies that are thought to be not reasonable for respectable people to hold. In my opinion, and feel free to disagree if you think I'm wrong, that also excludes single-payer health care. Numerous Democratic politicians (and, since it's relevant here, liberal bloggers) have expressed support for a single-payer system while choosing to work to pass and now support the ACA, based on an explicitly stated judgment that single-payer didn't have the votes. But as I said, if you disagree, make your case. And, other than health care, what else?
