As you know, Sarah Palin's been caught straight-up lying about deep-sixing the Bridge to Nowhere. And here's the transcript of her trying to explain the fib to Charlie Gibson ...

GIBSON: You have said continually, since he chose you as his vice-presidential nominee, that I said to Congress, thanks but not thanks. If we're going to build that bridge, we'll build it ourselves.

PALIN: Right.

GIBSON: But it's now pretty clearly documented. You supported that bridge before you opposed it. You were wearing a t-shirt in the 2006 campaign, showed your support for the bridge to nowhere.

PALIN: I was wearing a t-shirt with the zip code of the community that was asking for that bridge. Not all the people in that community even were asking for a $400 million or $300 million bridge.

GIBSON: But you turned against it after Congress had basically pulled the plug on it; after it became apparent that the state was going to have to pay for it, not the Congress; and after it became a national embarrassment to the state of Alaska. So do you want to revise and extend your remarks.

PALIN: It has always been an embarrassment that abuse of the ear form -- earmark process has been accepted in Congress. And that's what John McCain has fought. And that's what I joined him in fighting. It's been an embarrassment, not just Alaska's projects. But McCain gives example after example after example. I mean, every state has their embarrassment.

GIBSON: But you were for it before you were against it. You were solidly for it for quite some period of time...

PALIN: I was...

GIBSON: ... until Congress pulled the plug.

PALIN: I was for infrastructure being built in the state. And it's not inappropriate for a mayor or for a governor to request and to work with their Congress and their congressmen, their congresswomen, to plug into the federal budget along with every other state a share of the federal budget for infrastructure.

GIBSON: Right.

PALIN: What I supported was the link between a community and its airport. And we have found that link now.

We're at a key moment -- where we learn if there is any consequence in this election for serial lying. It's a question that only the major media outlets will be able to answer.
