Liberals have yet to realize that the mandate is out the window, and probably, the entire law as it never originated in the House. That said, there’s a zillion things left to litigate involving this monstrosity of a bill. Perhaps, though, we’ll be saved some of this by the House Republicans actually getting off their duffs and shutting down government until this tax bill is destroyed.
Unfortunately legally (not that that matters), the bill did originate in the House. Reid used the strategy of taking a House bill, stripping out its contents making it a shell bill and then putting Obamacare into the bill. This is a circumvention, but it has been done before and has precedent.
