Trump promised his supporters to repeal Obamacare . The Democrats spent 12 years in drafting it and forcing it through the senate. Trump is showing the way to do it faster and smarter by intentionally forcing the senate to get involved now. The vote will take place during the day with maximum TV coverage /intentional transparency so that the nah Republicans will be highlighted for all the world to see. Excellent strategy. If they foolishly disrupt the process, Trump will have a perfect basis for moving on tax cuts while the "want-a-be Presidential " dissenters trip over themselves.
