On Monday, the McCain campaign released an ad that repeats the false claim that Gov. Sarah Palin opposed the infamous Bridge to Nowhere in Alaska. In fact, she supported it 100 percent, when it was first introduced as a “pork” earmark on a bill by her mentor, Sen. Ted Stevens, Alaska’s senior senator who is currently facing bribery charges.

“You canâ€™t just recreate yourself. You canâ€™t just reinvent yourself. The American people arenâ€™t stupid.”

— Obama

At a campaign stop, Barack Obama took aim at the claim:

“Well, now, letâ€™s get the facts clear here,” Obama said. “When she was mayor, she hired a Washington lobbyist to get earmarks — pork barrel spending â€“- all the things that John McCain says is bad, she lobbied to get! And got a whole lot of it. When it came to the Bridge to Nowhere, she was for it until everybody started raising a fuss about it, and she started running for governor, and then, suddenly, she was against it! “You remember that?” Obama asked the Flinters. “‘For it before you were against it’? I mean you canâ€™t just make stuff up. You canâ€™t just recreate yourself. You canâ€™t just reinvent yourself. The American people arenâ€™t stupid.”

Appearing on MSNBC’s “Countdown” last night, Barack Obama repeated the attack, as you can see in the video at the top, and the second cut below:
