Palin's dilemma: Does personal loyalty trump conservative principles?

Now, Sarah Palin endorsing John McCain per se is understandable. I still don’t like it one bit, but I’ll cut her some slack. Remember, she threw in with McCain before conservative J.D. Hayworth entered the race. And with McCain expecting only token opposition from the Democrats in the general election, he was for a time the most conservative man in Arizona’s U.S. Senate race – if only technically and by default.

BUT…J.D. Hayworth is in the race now. He is a far preferable choice than McCain for conservatives on many issues, particularly immigration. Meanwhile, Palin has transitioned from merely supporting McCain (presumably out of a sense of loyalty) to actively stumping for the guy.

I thought Palin was supposed to be helping elect conservatives – not campaigning against them.
