Interesting, indeed. It may be a useful strategy for Democrats to support certain parts of the bill publicly. They may find it easy to sew or encourage divisions within the GOP ranks. Instead of being the new party of "no" like the GOP opposition before them, perhaps they can be the party of "yes, and..." There are so many ideological red lines for conservatives that countermand other ideological lines for other conservatives, that it may be easier to foment infighting than to just be intransigent. At least, that's what I'd do.
