Romney's cool and collected demeanor finally gave way to frustration and told Reid to finally back up his acidic accusations. Now let's see what the dishonest politician Reid does now. Does he put up or shut up?
Regardless of whether Reid is full of shit or not (he is), Romney is playing this the wrong way. He's legitimizing the claims and keeping the story alive by firing back which only gives people more reason to believe he's hiding something.
Reid is right in that the only possible way to settle it is for Romney to release 10 years of tax returns. If he doesn't plan on doing that, then Romney should have just responded as such: "Harry Reid said what? *laugh* Good for him. Next question."
