Obama has tried hard to distance himself from his campaign’s earlier statement in favor of the DC gun ban, but I think he’s nailed here. This time it isn’t an aide’s statement to be disavowed. Obama nods and says “right”, twice, as his interviewer asserts “you support the DC handgun ban and you’ve said that it’s constitutional.” He then spends over a minute focusing on more moderate gun-control measures that he supports, but never disputes the earlier assertion.
Hot Air has the YouTube video (search to 1:15 if you’re impatient).
The difference between then and now is, back then Obama was competing with Hillary Clinton for the votes of DC liberals. Back then, extreme gun-control positions paid. Now he wants to appear more centrist.
