Kentucky Senate candidate Rand Paul eloquently defends capitalism and free enterprise in his Republican primary victory speech.

Cities like New York and Washington are undergoing something of a baby boom as families increasingly settle in urban areas instead of the suburbs. This demographic development is causing new sorts of problems—like the relative unfriendliness of some city services to children—and conservatives need to be ready with real policy solutions for these young families.

It turns out Obamacare’s alleged Medicare savings don’t really add up to much. Too bad the AP tells us after the legislation passes.

Mother Jones’ May issue includes a truly astounding series of articles on population and sustainability that argues, explicitly, that Malthus was right after all. One article, not online, even goes so far as to suggest the government deliberately engineer a zero-GDP-growth economy, a scheme even the author admits suffers from more than a few conceptual and practical flaws.

Heather Mac Donald swats down the New York Times’s sloppy accusations of NYPD racism: “The actual crime rates reveal that blacks are being significantly understopped, compared with their representation in the city’s criminal population, another reason for omitting them from the paper’s reporting.”

And last but not least, Megan McArdle explores whether obesity is as much of a problem as the worrywarts tell us. The surprising conclusion: not really, and we can’t do much about it anyway.

Charles Kesler has an important article in the May 17 issue of National Review (republished online over at Claremont Conservative) on the importance of constitutionalism. The penultimate paragraph highlights the importance of restoring the Constitution to its rightful place:

In the current crisis, conservative efforts to restore the separation of powers may even be more important than a campaign to shore up federalism. TARP, for example, was an unprecedented delegation of legislative power to the Treasury secretary, of all people. It was a desperate, essentially lawless grant resembling the ancient Roman dictatorship, except that the Romans wisely confined their dictators to six-month terms. Obamacare is a 2,000-page monstrosity that will need thousands, perhaps tens of thousands, of pages of additional regulations before it can operate. These will be issued by more than a hundred new bureaucracies, each a source of unaccountable power wielded over individual Americans. These multiplying centers of petty tyranny will accelerate our transformation from a republic of laws to a corrupt régime of muddled and ever more arbitrary power.

Tim Ferriss offers advice for dealing with online critics, much of it based on the axiom that you can’t please all the people all the time.

The Library of Congress’ online catalog includes several great old pictures of Dupont Circle, including this one of the circle before the fountain was installed:

Sean Fieler and Jeffrey bell ask whether we should revisit the gold standard as one way to rein in runaway government.

Last but not least, Reihan Salam explores whether legislation to limit ATM fees will be counterproductive. He cites a fun article on the topic by Thomas Hazlett, who sarcastically asks, “can anyone explain why at a price of $0, quantity supplied is nil?”

Saturday Night Live takes on public-sector unions in this hilarious sketch.
