That is the perfect rejoinder to an utterly ridiculous headline question.
Which of the two liberals would govern more conservatively? Bah! If this is what we're left to choose from, the biggest loser is conservatism.
This is being setup as a repeat of 2008. Which one in the primaries do we choose: McCain or Romney? That's a tough one. The question they should be asking is which one is less liberal than the other?
How about neither while there's still time?
