I look at what a miserable lineup we have in the Pelosi-Reid-Obama axis, and think it's very clear that Palin is a far cry from those incompetent frauds. I think she would be a strong candidate for a range of higher offices.
The big problem for Palin is that, in the American electoral system as currently constituted, she's not really all that good a fit with the Republicans. She fought entrenched old-time Repubs too successfully in Alaska for them to all just kiss & make up. And of course she's not a bit like modern Democrats. So where exactly would her power base lie?
Actually, we really don't know all that much about Candidate Palin. As usual, most of what we think we know is really projection onto our candidates of what we hope to see. And of course there is no shortage of loudmouth numbskulls who are happy to tell us all what they see projected on the candidate, but this is just noise, and of no value.
It's possible that Palin's decision to proceed with the birth of her youngest son marks her as a person with an ethical sense several orders of magnitude stronger than anyone we've seen in American politics for many years. Some are doubtless terrified of the implications, others are intrigued.
