Talking about Romney:
“As president,” Obama added, “one of the things I’ve learned is you can’t do that. That it’s important for you to make sure that the statements you make are backed up by the facts.”
STFU fecist.
It's called "not lying".
Most people learn that soon after they are out of diapers.
Obama didn't learn it until he was 47 and elected to the presidency?
Actually, he might have learned he is not supposed to lie, but he still does it regularly anyway.
