I don't care what other people believe, and what other people are saying. I'm talking about what Palin said, and what Palin believes. And secondarily, what you believe she really meant.
There is apparently a legitimate discussion over the differences among the Constitutional definition the VP's role, the historical practice, and the modern practice. You're either: deflecting the conversation away from "what did Palin say/mean" into this tangentially related question, and thinking I won't notice; or asserting that Palin was referring to this issue herself, and thinking I'll believe you really mean it.
So which is it? Are you insulting my intelligence by changing the subject, or insulting my intelligence by offering an argument that you don't believe yourself?
