The author of this article doesn't even allow for the possibility that she could run for the Senate in 2006 and be beaten by Rudy Guiliani.
This article is garbage from a journalistic perspective, and just talking points from her campaign.
The author states the case against Hillary in the first half, and then tries to systematically disprove it point-by-point in the second half, culminating in the final quote about her improving poll numbers.
The interesting point, though, is the quote from her about being "polarizing", when she says "We have a president who is quite polarizing - and very successful, I might add." That is her angle for 2008, to counter the questions about her "electability."
