Politicians love dynasties. Let’s call it incumbency-squared.

In America, we’ve had either a Bush or a Clinton serving in the nation’s highest office for the last two decades. Should Hillary Clinton win the presidency and serve for two full terms, America would have three decades, 28 years, of presidents from just these two families.

Yes, even here, in a republic, there are reasonable worries about dynastic rule.

At least, though, we have presidential term limits.

But then, so does Argentina. And the new president-elect of Argentina, Cristina Fernández de Kirchner, is the wife of the current president, Néstor Kirchner. The couple has decided to alternate runs for the position, thereby weaseling around the country’s term limit of two consecutive terms. This way, they can rule for an indefinite period.

The Peronistas of Argentina express excitement. But Argentineans with sense should not.

And plenty of Argentineans do worry, especially the 55 percent who voted for someone else. They blanch at the flash and dazzle in the last campaign, the lack of substance. They even talk about Christina’s hair extensions, make-up, and quick-change wardrobe.

But they should worry most about the principles involved.

Don’t cheer for Cristina, Argentina. Term limits aren’t something to squirm out of. They are to be treated with respect. The benefit is blocking the monopolization of power.

When the news came out that the next session of Congress would have a shorter work week, a lot of people unleashed their Inner Scoffers. The country’s in a mess, and the Democrats in Congress want to work less!

But hey: The 110th Congress — the one we are currently enduring — started out with the promise to end the meager two-day work week, to work harder. A lot did come out. But what of value?

And now all we have to look forward to is . . . Fridays off for the upcoming year?

Well, in June, at money time, our representatives will put back on the Friday yoke. But otherwise it’s back down to four days of sessions per week.

This could actually be good. The answer to our problems is probably not more from Congress, but less. Less government spending. Fewer laws. No new programs.

Indeed, the only excuse for more work is to fix the biggest problems Congress has given us — like Social Security, for instance . . . and Medicare . . . farm subsidies, of course . . .  and the bottlenecks of transportation regulation.

Maybe Congress should go back to working two days only — if they would add a special day every month devoted to repealing the bad stuff they did in previous years.

But would that provide time enough to repeal enough?

That five-day work week would probably have to be revived.

This is Common Sense. I’m Paul Jacob.
