As several commenters below have noted, the Senate repealed the odious “don’t ask, don’t tell” policy yesterday, paving the way for gays to serve openly in the U.S. military.

I’m not a fan of Joe Lieberman, as you may know, but he deserves props here; he’s been a forceful advocate of repeal. (Just to remind you of why I can’t stand him: He also suggested that the New York Times should be prosecuted for publishing articles related to the Wikileaks documents. Argh.)

Unfortunately, at the same time Republicans in the Senate blocked what has become known as the Dream Act, legislation that would establish a path to citizenship for illegal immigrants who came to the country as children. Drew Faust has been a supporter of the bill.

Still, the DADT repeal is a watershed in the nation’s civil rights history…

“I don’t care who you love,” Senator Ron Wyden, Democrat of Oregon, said as the debate opened. “If you love this country enough to risk your life for it, you shouldn’t have to hide who you are.

…and marks the for-all-intents-and-purposes end to John McCain’s career as a credible public figure.

“I hope that when we pass this legislation that we will understand that we are doing great damage,” Mr. McCain said. “And we could possibly and probably, as the commandant of the Marine Corps said, and as I have been told by literally thousands of members of the military, harm the battle effectiveness vital to the survival of our young men and women in the military.”

Once President Obama signs the bill, it will presumably have rapid ripple effects—such as the return to Harvard of ROTC. That action will ease a profound social tension for the university, whose stand on principle cost it amidst the broader culture, and for its president, who gets to oversee an act that costs nothing but brings enormous rewards. One thing you have to say about Drew Faust: Her life has been marked by a propensity to be in the right place at the right time.

Is it possible, by the way, that by the time November 2012 rolls around, the American public will realize that Barack Obama has been the most effective, active, accomplished American president since FDR??
