Interesting poll by Zogby asking respondents whom they would absolutely not vote for in the general election, including candidates from both parties.

Not great news for the HRC camp. Interesting favorability for Huckabee (watch out for him). Richardson did best, and Obama did well also.

UPDATE: I see there has been debate over the validity of this poll due to the fact that it was an online poll. Just to clarify, this wasn't a typical online poll that one may find on msnbc.com, for example, which can be easily freeped. The poll was conducted with registered Zogby members who enter demograpic information upon registration and are invited to particular polls.
From Zogby's website:
Zogby International commissioned an online survey of [9976 likely voters].
A sampling of Zogby International's online panel, which is representative of the adult population of the US, was invited to participate. Slight weights were added [region, party, age, race, religion, gender] to more accurately reflect the population. The margin of error is +/- 1.0 percentage points. Margins of error are higher in sub-groups.
Perfect? No. But not much worse, if at all, than a telephone poll
