In between saying that he's "a big supporter of waterboarding" and that President Obama owes his predecessor "a healthy dose of 'thank you, George Bush,'" former Vice President Dick Cheney said something recently on ABC's "This Week" that made uncommon sense to Washington Post columnist Eugene Robinson: that it's time to "reconsider" the "don't ask, don't tell" ban on gays in the military and that he believes the policy will change. "I think the society has moved on," said Cheney, a former secretary of defense. "I think it's partly a generational question."Robinson concluded: "Cheney's burst of lucidity should help Republicans in Congress understand that there is no longer any reliable constituency for the troglodyte position on 'don't ask, don't tell.' If a long-overdue policy shift that would allow gay people to serve openly in the armed forces is fine with three-fourths of the American public, the top officers in the Pentagon hierarchy and Dick Cheney, too, then the times aren't just a-changing. They've already changed."
