They broke it. Now they own it.

Republicans have won total control over the federal government for the first time in a decade. Two interconnected revolutions have shattered the old order in Washington and brought the country to a fresh political juncture: The tea party movement that gave a new breed of confrontational conservative decisive sway on Capitol Hill starting six years ago, and now the extraordinary triumph of the infuriated outsider personified with the election of Donald J. Trump.

The congressional wing of the GOP and the nation’s 45th president will face an enormously difficult task starting in January. They will have to blend their surprisingly divergent priorities, and their emphatically dissonant ideologies, so that they can set about fulfilling the fundamental promise they do agree on — putting Washington back in good working order.

The new generation of Republicans who now assert the party’s balance of power on the Hill, and the Republican who just laid claim to the White House without any prior experience in government whatsoever, all got to where they are by railing against dysfunctional business as usual — a capital where deadlock is an acceptable default setting, meaning little gets done in the eyes of the average American.

Now Trump and the 115th Congress will have just 22 months, until the next midterm election, to prove their capacity for breaking the gridlock they all ran against.
