At this point, all Democrats might need do is just sit back and watch Republicans self-destruct. Republicans haven't been able to repeal and replace Obamacare or deliver any of the fiscal stimuli they have promised (e.g. tax cuts and simplification, infrastructure spending, 3% or better economic growth, balanced budget, better and less expensive healthcare, etc.). Republicans have yet to be able to deliver on any of their promises other than to appoint another knuckle-dagger to the Supreme Court. Republicans are now threatening to repeal Obamacare without a replacement, which would be yet another instance in which they break a campaign pledge. So if they want to kill Obamacare and deny healthcare insurance to millions of their constituents; go for it. But it's not only morally wrong; it's politically and economically stupid. Republicans have not a single plan to improve the quality of life for the folks who elected them, and then of course there is the whole matter of incompetency. Democrats may need to do nothing except watch Republicans self-destruct.
