CHUTZPAH WATCH…. Starting with her very first appearance as a candidate for national office, Sarah Palin claimed to have told Congress, “Thanks, but no thanks” when it came to the infamous Bridge to Nowhere. Almost immediately, Americans learned that the claim was demonstrably false. Palin, McCain, and their surrogates repeated it anyway.

Last week, pressed by ABC’s Charlie Gibson, Palin walked the claim back a bit. Apparently, old habits die hard, because there Palin was again today, speaking in Colorado, telling the same lie all over again.

I suspect the McCain campaign assumes that it’s easier to get away with a brazen lie by repeating it ad nauseum — reporters will simply get tired of calling the liar out. No news outlet wants to republish the same story — “Palin still lying about infamous bridge” — every day for three weeks.

And so, Palin just keep telling the lie, hoping her supporters are fools, and thumbing her nose at reporters who clearly, by now, know the truth.

It remains breathtaking.
