Is the McCain campaign conceding that their claims on the Bridge to Nowhere were lies?

I was just thinking about last night's debate, and it struck me that Palin dropped two of her signature claims to fame. The assertion that she said "no thanks" to the Bridge to Nowhere, and her anecdote about putting the state plane on eBay.

What gives? Were they perhaps concerned that Joe Biden might point out that the Bridge to Nowhere story is a complete lie, or that the eBay story is a huge piece of puffery?

Maybe they hope that no one noticed. I do think that if Palin begins making either two claims again someone should ask her why she was silent on these topics at the debate, or maybe just why she's lying. But of course, that would mean taking questions from a reporter, and that's something that Palin just doesn't do very often.
