"Obamacare's not imploding. The main goal of Obamacare was two-fold. One was to cover the uninsured, of which we've covered 20 million, the largest expansion in American history. The other was to fix broken insurance markets where insurers could deny people insurance just because they were sick or they had been sick. Those have been fixed, and for the vast majority of Americans, costs in those markets have come down, thanks to the subsidies made available under Obamacare."
