Hillary's Negative Numbers

From Chuck Todd:

Hillary Clinton is sporting the lowest personal ratings of the campaign. Moreover, her 37 percent positive rating is the lowest the NBC/WSJ poll has recorded since March 2001, two months after she was elected to the U.S. Senate from New York.

So, if in the course of her bid to become president, Clinton is actually sinking in popularity, what does this say about her chances of actually winning in the general election?

More numbers:

When asked if the three presidential candidates could be successful in uniting the country if they were elected president, 60 percent of all voters believed Obama could be successful at doing this, 58 percent of all voters said McCain could unite the country while only 46 percent of voters said the same about Clinton.

As someone who voted twice for Hillary's husband, and once for the former first lady herself, in the state of New York (I would have twice, but I moved to Florida before the second election), these negatives jumped out as a big concern when our present contest began. The fact is that Clinton remains a polarizing figure in American politics, and nothing she has done in this campaign so far has significantly revised this perception.

Are there good reasons to vote for her, sure, just as there are good reasons to vote for Obama and McCain. But it seems fairly clear to me that in the remaining months of what has devolved into a negative campaign, her approval ratings will only slip further away from that magic 50%. Simply put, it just isn't possible to win the presidency with a 37% approval rating.
