Nothing really new, here:  I'd just like to emphasize something we all already know.  Senator Clinton and Senator McCain, in the matter of the proposed "Gas Tax Holiday", are deliberately lying to us because they think that we're stupid, and are more likely to vote for them if they tell us this particular lie.  They're doing this pretty much right out in the open, without any cover at all; neither of them has been able to round up a single creditable economist to support the plan, and neither has bothered to give us a coherent reason why they're right and all the economists in the world are wrong.  
This is the sort of behavior we've come to expect from Republicans; and it's the kind of thing that's soured so many of us on Senator Clinton.  Hillary might just as well come right out and say "If you vote for me, magical fairies will sprout from my forehead, and we will use their urine to power our machines."  It would show just as much respect for our intelligence as her current proposal.
Paul Krugman, an economist who supports Senator Clinton, admits that her proposal is farcical.  He claims it doesn't matter, though, because she doesn't really believe it and has no intention of keeping her promise.  That's... really sort of sad, isn't it?
