No, its not a "blow" to President Trump.  As usual, the Fake News that predicted an easy  election win for Clinton is wrong.  This is a huge win for Trump and his agenda of change.  

Obama took over 20 months to get Obamacare done.  This is long, complex process.  And unlike Obama, Trump has to fight past the establishment elites, the obstructionist Democrats, the swamp and the Fake News who are all trying desperately to stop his agenda.

This is a game of high stakes chess. And Trump is playing 8D chess while his opponents are playing checkers and the Fake News is still looking for the checkerboard.
