Trump is gleeful that a Texas judge has ruled Obamacare unconstitutional. It remains to be seen whether this gets to the Supreme Court and whether its new conservative majority decides to prolong the shameful fact that the USA is the only developed country not to have a universal and affordable healthcare system.
But this is fantastic campaign fodder for the Democrats. If the Republicans in the Senate or the White House block any democratic attempt to introduce some kind of affordable care in the House, or if the Republicans do not come up with a viable plan of their own, they will lose in 2020.
