In my view, the first position — that we can contain Iran as we did the Soviet Union — is totally wrong, a product of wishful thinking and misread history. But at least it’s internally coherent.

What’s alarming is not just Iran’s increasing store of enriched uranium or the growing sophistication of its rocketry. It’s also the increasingly menacing annihilationist threats emanating from Iran’s leaders. Israel’s existence is “an insult to all humanity,” says President Mahmoud Ahmadinejad. “Anyone who loves freedom and justice must strive for the annihilation of the Zionist regime.” Explains the country’s Supreme Leader Ayatollah Ali Khamenei, Israel is “a true cancer tumor on this region that should be cut off.”

They haven’t had a decisive influence since Lyndon Johnson carried Texas for John Kennedy in 1960. (That and Illinois put Kennedy over the top.) This time, however, the effect could be significant. The Democrats’ Mediscare barrage is already in full swing. Paul Ryan, it seems, is determined to dispossess Grandmother, then toss her over a cliff. If the charge is not successfully countered, good-bye Florida.

The stewardship case is pretty straightforward: the worst recovery in U.S. history, 42 consecutive months of 8-plus percent unemployment, declining economic growth — all achieved at a price of an additional $5 trillion of accumulated debt.

Not quite the naked ethnic appeal of yore. Each destination suggests a somewhat more subtle affinity: Britain, playing to our cultural connectedness with the Downton Abbey folks who’ve been at our side in practically every fight for the last hundred years; Poland, representing the “new Europe,” the Central Europeans so unashamedly pro-American; Israel, appealing to most American Jews but also to an infinitely greater number of passionately sympathetic evangelical Christians.

And who might that somebody else be? Government, says Obama. It built the roads you drive on. It provided the teacher who inspired you. It “created the Internet.” It represents the embodiment of “we’re in this together” social solidarity that, in Obama’s view, is the essential origin of individual and national achievement.

Poor Solicitor General Donald Verrilli.Once again he’s been pilloried for fumbling a historic Supreme Court case. First shredded for his “train wreck” defense of Obamacare’s individual mandate, he is now blamed for the defenestration in oral argument of Obama’s challenge to the Arizona immigration law.

At the beginning of his presidency, Barack Obama argued that the country’s spiraling debt was largely the result of exploding health-care costs. That was true. He then said the cure for these exploding costs would be his health-care reform. That was not true.

Now it’s back, summoned to the national stage by the confluence of three disparate events: the release of new Congressional Budget Office cost estimates, the approach of Supreme Court hearings on the law’s constitutionality and the issuance of a compulsory contraception mandate.

Five have come and gone, if you count the Donald’s aborted proto-candidacy. And now the sixth and most plausibly presidential challenger just had his moment — and blew it in Michigan.

— former presidential candidate Rick Perry

It’s the campaign line of the year, and while the author won’t be carrying it into the general election, the eventual nominee will.

Romney won a major victory with nearly 40 percent of the vote, 16 points ahead of No. 2. The split among his challengers made the outcome even more decisive. Rick Santorum and Newt Gingrich were diminished by distant, ­lower-tier finishes. Rick Perry got less than 1 percent. And Jon Huntsman, who staked everything on New Hampshire, came in a weak third with less than half of Romney’s vote. He practically moved to the state — and then received exactly one-sixth of the vote in a six-man contest. Where does he go from here?

To begin with, what even minimally rational government enacts payroll tax relief for just two months? As a matter of practicality alone, it makes no sense. The National Payroll Reporting Consortium, representing those who process paychecks, said of the two-month extension passed by the Senate just days before the new year: “There is insufficient lead time to accommodate the proposal,” because “many payroll systems are not likely to be able to make such a substantial programming change before January or even February,” thereby creating “substantial problems, confusion and costs.”

— Barack Obama, Dec. 8

Fair enough. Barack Obama didn’t appease Osama bin Laden. He killed him. And for ordering the raid and taking the risk, Obama deserves credit. Credit for decisiveness and political courage.

When three-quarters of Americans think the country is on the “wrong track” and even Bill Clinton calls the economy “lousy,” how then to run for a second term? Traveling Tuesday to Osawatomie, Kan., site of a famous 1910 Teddy Roosevelt speech, Obama laid out the case.

Romney has managed to weather the debates unscathed. However, the brittleness he showed when confronted with the kind of informed follow-up questions that Bret Baier tossed his way Tuesday on Fox’s “Special Report” — the kind of scrutiny one doesn’t get in multiplayer debates — suggests that Romney may become increasingly vulnerable as the field narrows.

His near-$1 trillion stimulus begat a stagnant economy with 9 percent unemployment. His attempt at Wall Street reform left in place a still-too-big-to-fail financial system, as vulnerable today as when he came into office. His green-energy fantasies yielded Solyndra cronyism and a cap-and-trade regime not even a Democratic Congress would pass.

To be sure, Tuesday was not exactly the Democrats’ night. They did enjoy one big victory, repeal of government-worker reform in Ohio. But elsewhere, they barely held their own. The bigger news was the absence of any major Republican trend. The great Republican resurgence of 2009-10 has slowed to a crawl.
