Barack Obama’s legacy is being systematically unraveled even before he leaves office, with The Wall Street Journal scoffing that he “has been a historic president but perhaps not a consequential one.”

Historians will also note that the Democratic Party is in far worse shape today than when Obama took office: It has lost its House and Senate majorities, as well as 13 governorships and more than 900 state legislative seats.

More broadly, the sunny Obama optimism of “Yes, we can” has faded into a rancorous miasma of distrust and dysfunction. One example of that rancor is unfolding at the Woodmont Country Club outside Washington, where hawkish pro-Israeli members are campaigning to deny Obama membership — even though there’s no official indication he will even apply.

Yet here’s my prediction: America and the world will soon be craving that Obama Cool again.

Voters are fickle and promiscuous, suffering an eight-year itch for a fling with someone who is the opposite of their last infatuation. Sick of Bill Clinton, we turned to a Texas governor who was utterly different. Eight years later, weary of George W. Bush, we elected his polar opposite, a liberal black law professor. And now we’ve elected Obama’s antipode.
