Palin’s personal opinion means a lot, because she could be POTUS some day, and she will be an important advisor to McCain.
Putting aside the fact that you're skipping completely over what we already know John McCain to be, and ignoring the fact that he's already openly admitted to you that his first and most important act will be to "reach across the aisle," in the short run, her opinions only carry the weight that John McCain gives them. In the long run, she's already shown that she shares his views concerning the false federalism that alienates unalienable rights. So, it looks to me like a lose-lose.
