Watching Dick Cheney defend the Bush administration’s interrogation policies, it’s been hard to escape the impression that both the Republican Party and the country would be better off today if Cheney, rather than John McCain, had been a candidate for president in 2008.

Certainly Cheney himself seems to feel that way. Last week’s Sean Hannity interview, all anti-Obama jabs and roundhouses, was the latest installment in the vice president’s unexpected  and, to Republican politicians, distinctly unwelcome  transformation from election-season wallflower into high-profile spokesman for the conservative opposition. George W. Bush seems happy to be back in civilian life, but Cheney has taken the fight to the Obama White House like a man who wouldn’t have minded campaigning for a third Bush-Cheney term.

Imagine for a moment that he’d had that chance. Imagine that he’d damned the poll numbers, broken his oft-repeated pledge that he had no presidential ambitions of his own, and shouldered his way into the race. Imagine that Republican primary voters, more favorably disposed than most Americans to Cheney and the administration he served, had rewarded him with the nomination.

At the very least, a Cheney-Obama contest would have clarified conservatism’s present political predicament. In the wake of two straight drubbings at the polls, much of the American right has comforted itself with the idea that conservatives lost the country primarily because the Bush-era Republican Party spent too much money on social programs. And John McCain’s defeat has been taken as the vindication of this premise.
