Do we have a president or a perpetual candidate? It's not an entirely unfair question.

Even as Barack Obama was warning of the dreadful consequences of the budget sequester looming on March 1, he spent days away from Washington, apparently out of touch with Democratic as well as Republican congressional leaders.

In the meantime, Obama fans were lobbing verbal grenades at none other than The Washington Post's Bob Woodward.

The latest dispatch from the food wars: For those at high risk of heart disease, following the Mediterranean diet results in 30 percent fewer heart attacks and strokes. Focused on nuts, beans, fatty fish, fruits and vegetables -- all washed down with olive oil and wine (separate glasses, please) -- the diet is said to be more effective in combating cardiovascular disease than the low-fat regimens now in vogue.   

To borrow a phrase, Mainstream America and Washington's Political Class have become two nations separated by a common language. This gap was highlighted by a recent Pew Research Center poll showing that "for 18 of 19 programs tested, majorities want either to increase spending or maintain it at current levels."

Indebted America is in danger of turning into destitute Greece, or so congressional Republicans and conservative commentators have been warning us for years now. For many reasons, this is an absurd comparison -- but it may not always be quite so ridiculous if Washington's advocates of austerity get their way

The Republicans actually want to impose Greek-style budget slashing on the United States. And the federal budget sequestration scheduled to take effect next week could represent the first serious step here toward the kind of fiscal policies that have proved so ruinous not only in Greece -- raising unemployment, destroying hope and encouraging extremism -- but across Europe.

Barack Obama is said to believe that he can win the political fight over the sequester. That's certainly the conventional wisdom. 

Last week, Conservative pundit Ann Coulter told me and a thousand young libertarians that we libertarians are puss- -- well, she used slang for a female body part.

We were in Washington, D.C., at the Students for Liberty conference, taping my TV show, and she didn't like my questions about her opposition to gay marriage and drug legalization.

"We're living in a country that is 70 percent socialist," she says. "The government takes 60 percent of your money. They take care of your health care, your pensions ... who you can hire ... and you (libertarians) want to suck up to your little liberal friends and say, oh, we want to legalize pot? ... If you were a little more manly, you'd tell liberals what your position on employment discrimination is."

When folks pan the Affordable Care Act for being nearly 3,000 pages long, here's a sensible response: It could have been done in a page and a half if it simply declared that Medicare would cover everyone.

The concept of Medicare for All was pushed by a few lonely liberals. And it would have been, ironically, the most conservative approach to bringing down health care costs while maintaining quality.

For years, most Americans' vision of history has been shaped by the New Deal historians. Writing soon after Franklin Roosevelt's death, Arthur Schlesinger Jr. and others celebrated his accomplishments and denigrated his opponents.

They were gifted writers, and many of their books were bestsellers. And they have persuaded many Americans -- Barack Obama definitely included -- that progress means an ever bigger government

There's a panic bubbling to the surface in Washington, D.C.

It's being brought about by the so-called sequester, scheduled to take effect next Friday, March 1. The sequester, a series of automatic across-the-board spending reductions, is a gimmick the politicians came up with in 2011 to force themselves to reach some kind of long-term deficit reduction deal.

One of the interesting things about recent elections is that Republicans have tended to do better the farther you go down the ballot.

They've lost the presidency twice in a row, and in four of the last six contests. They've failed to win a majority in the U.S. Senate, something they accomplished in five election cycles between 1994 and 2006.

But they have won control of the House of Representatives in the last two elections, and in eight of the last 10 cycles.

And they've been doing better in elections to state legislatures than at any time since the 1920s.
