Plausible deniability.....
Here's a question for you: Is Hillary Clinton for or against the War in Iraq?
Answer: That depends on who is asking the question.
Its true though - Romney is a very weak debater. Way too wishy-washy. But that's guff that I have will all of the Republican candidates (unless you count Mr. Ron Paul... but um.... he's Ron Paul....). None of them have the guts to say it like it is.
But then again,

of those questions are rigged (surprise surprise its CNN)- designed to make the candidate look bad whichever answer they give. These mass-appeal debates are therefore, for the most part, completely pointless anyways. Its not about what a candidate wants to do as policy - its about how they can avoid all the laid traps of public speaking.
P.S. (another huuuuge surprise here.... /sarcasm) Hillary plants question in Republican debate:
