She sees, I think, the degeneracy of the party she supports and the unseriousness of large swathes of the other party. In ordinary times, this might be par for the course.

Part of me wants McCain to be defeated as a Republican nominee by the forces that have helped bring us to this point. Then we can have a centrist reformer who does not even have to lip-sync respect for the elements that have helped destroy a coherent conservatism and a united country. And he would be the most formidable third-party candidate in a very long time. And part of me sees him as the only way to rescue the Republicans from what they have become. It will be their choice. And it will be an interesting one.
