Charles Davis writes: More than three years into the presidency of Barack Obama, it’s almost a cliché now to ask: What if George W. Bush did it? From dramatically escalating the war in Afghanistan to institutionalizing the practice of indefinite imprisonment, Obama has dashed hopes he would offer a change from the Bush’s national security policies – but he hasn’t faced a whole lot of resistance from liberals who once decried those policies as an affront to American values.

Like those on the right who now crow about fascism but spent the Bush years gleefully declaring left-wing celebrities “enemies of the state,” many of those on the liberal-left treat issues of war and civil liberties as useful merely for partisan purposes. When a Democrat’s in power those issues become inconvenient. And usually ignored.

Former dean of the Yale Law School Harold Koh, for instance, used to rail against the imperial presidency, speaking of the horror of torture and “indefinite detention without trial.” Now a legal adviser for the Obama State Department, he recently declared that “justice” can be delivered with or with out a trial. Indeed, “Drones also deliver.” Don’t expect much more than a yawn from Democratic pundits, though, much less any calls for impeachment. It’s an election year, after all. And what, would you rather Mitt Romney be the guy drone-striking Pakistani tribesmen?

“Obama and the Democrats being in power in Washington defangs a lot of liberal criticism,” Chase Madar, a civil rights attorney in New York, told me in an interview. Indeed, but with a few exceptions – Michael Moore, Dennis Kucinich, The Nation – those who would be inclined to defend Manning were Bush still in office are the ones either condemning him or condoning his treatment, which has included spending the better part of a year in torturous solitary confinement, an all too common feature of American prisons. Even his progressive defenders, remaining loyal to the Democratic Party, tend to downplay Obama’s role in the Bradley Manning affair; his authorizing the abuse of an American hero is certainly no means not to vote for him again.

“The whole civil libertarian message only really seems to catch fire among liberals when there’s a Republican in the White House,” says Madar. When there’s not a bumbling Texan to inveigh against, all the sudden issues that were morally black and white become complex, and liberal media starts finding nuance where there wasn’t any before.
