Congress quickly passed a bill giving Obama reallocation authority to restore air traffic control. Having previously threatened to veto any such bill, Obama caved. He signed.
Not exactly Appomattox, but coming immediately after Obama's spectacular defeat on gun control, it marked an administration that had lost its "juice," to paraphrase a question at the president's news conference.
For Obama, gun control was a political disaster.
He invested capital, went on a multicity tour, paraded grieving relatives. And got nothing.
An assault-weapons ban — a similar measure had passed the Congress 20 years ago — lost 60-40 in a Senate where Democrats control 55 seats. Obama failed even to get mere background checks.
All this while appearing passive, if not helpless, on the world stage.
On Syria, Obama was nervously trying to erase the WMD red line he had so publicly established.
On Benghazi, he stonewalled accusations that State Department officials wishing to testify are being blocked.
He is even taking heat for the Boston bombings. Every day brings another revelation of signals missed beforehand.
And his post-bombing pledge to hunt down those responsible was mocked by the scandalous Mirandizing of Dzhokhar Tsarnaev, gratuitously shutting down information from the one person who knows more than anyone about possible still-existent explosives, associates, trainers, future plans, etc.
Now, the screw will undoubtedly turn again. If immigration reform passes, Obama will be hailed as the comeback kid, and a new "Obama rising" narrative proclaimed.
This will overlook the fact that immigration reform has little to do with Obama and everything to do with GOP panic about the Hispanic vote.
In fact, Obama has been asked by congressional negotiators to stay away, so polarizing a figure has he become.
Whatever happens, the screw will surely turn again, if only because of media boredom.
But that's the one constant of Washington political life: There are no straight-line graphs. We live from inflection point to inflection point.
And we've just experienced one. From king of the world to dead in the water in six months.
Quite a ride.
