Here are some of the new reasons:
1. Steps on the story of Obama’s speech (and convention), and possibly the bounce coming from them, and wipes them off the news cycle. The Sunday news shows will be all-Palin, all of the time.
9. Revives some of the double-edged nature of the Democratic primary, which featured a black vs. a female trail-blazer, and put both sides on notice on sensitivity issues. Democrats used to raising charges of racism against Obama’s critics may face charges of sexism and/or condescension if they try to diss her.
14. Counter-intuitively, makes the issue of Obama’s light resume more potent than ever. Her lack of experience is no more than his is. And he’s--to use a term from Alaska, and the Iditarod--their lead dog.
