It wasn't the first time..

...that Obama let his true intentions slip...

Q: When you were in the state senate, you talked about licensing and registering gun owners. Would you do that as president?

A: I don't think that we can get that done.

No unequivocal "yes" or "no," just a mealy-mouthed admission that it wasn't feasible at the time. Based on his record, I'd go with a "yes," but I'm just cynical that way, I suppose.
You can see this exchange in this clip (at 5:01) of Chris W. Cox's blistering speech at the NRA convention this year, from which comes a killer quote:
"Folks, Barack Obama is just as radical as Hillary Clinton. He's just not as experienced at lying about it yet."
A-yep...
