Who the fuck put up Bob Casey against Santorum?

For the love of god, I'm watching Meet the Press and based on this interview, I wouldn't vote for either of these schmucks! Why, when they asked Santorum about Iraq and terrorism, and he responded with IranIranIran didn't Casey come back with "What you've just heard is Senator Santorum following the talking point memo he got that says IranIranIran 24/7 - and doesn't address any of the issues of the current war in Iraq that we got into (that has nothing to do with the war on terrorism), nor does it address the war on terrorism! Iran is another upcoming problem that this administration is rapidly exacerbating on the horizon, and based on how they've handled Iraq, Afghanistan, and the war for the hearts and minds of people across the globe, including right here in the US, I wouldn't trust them with grooming my DOG, let alone trying to finesse a delicate situation in Iran!"
