A not so good development.
McCain/Palin lying has been so regular and sustained it's no longer "news". It's "dog bits man" and thus not reported by big media.
ABC is an exception, but the 'Carved B' hoax is getting a complete pass. FactCheck.org is routinely calling the lies, but they're running out of euphemisms and migrating to descriptions like "whopper". Alas, they're not mainstream.
I put Obama's chances at no more than 50%, so this is not a good time for the big buys to stop pointing out that Palin and McCain are non-stop liars.
