This article is about the fact that women over 40 are not voting for Obama as they normally would. McCain is winning among those women. He is going to pull in larger numbers by the time this campaign ends.
The author thinks that putting Hillary on the ticket helps and it may but it would probably not help much. Women vote the top of the ticket not the bottom and Obama hasn’t addressed his own sexism. He also never apologised to Hillary and Bill and until he does and he means it this woman will never vote for him.
