I agree that she is probably doing it to show loyalty (which McCain does not deserve). I disagree that it is the right move.
She could show loyalty by not campaigning for any of his primary opponents.
I often ask myself, “What would Reagan do?” I get the feeling Sarah does too. I rarely recall Reagan, except when on the campaign trail and someone would be heckling him, or perhaps in his tailored responses to foreign dictators...get angry or ever lose his cool. He never was petty, when I think he could have been.
So far Sarah has been Christ like in her patience with the left and people like Letterman etc.
There’s no reason for her to alienate a major wing or the electorate.
Therefore, she can either NOT campaign, or come forth now..and say with conviction that she will when she’s been asked.
She’s doing the right thing.
