You are being obtuse. She was asked a question that had a simple yes or no answer, she knew a yes would kill her but she didn't want to say an outright no so she waffled. This question my have surprised her but if she was really a conservative she would have said no flat out. She is now trying to back pedal.
Let me ask you this: If you were talking to a stranger on a bus and he asked you the same question would you be so surprised you waffled and made it sound as if you were hiding a "yes" answer behind the waffle? I bet you wouldn't but here you are trying to make excuses for someone who is running for public office and doesn't have the fortitude to answer such a simple question with a flat out no.
If she has no more expertise than that she doesn't need to be running for Governor. I know if I was living in Texas I would not vote for her, but that's just me.
Her hesitation to answer one way or the other makes me think she was quickly reviewing in her mind all of her previous statements on the subject to weigh whether or not those statements could be held against her.
If you have to pause to think about what you've said previously and whether or not it can be used against you, then you are probably lying. That's my gut feeling on this one.
I just don't think she went into an interview with Glen Beck ill-prepared. She shined in the debates. She was prepared and focused. There's no way this was an off-the-cuff mistake. She hesitated because she knew she'd said something to someone that could hurt her politically.
