NBC/WSJ poll: Doubts about Palin

From NBC's Mark Murray
The new NBC News/Wall Street Journal poll will be released at 6:30 pm ET, but here's an early look at one set of numbers:

Forty-nine percent say that Palin is unqualified to be president if the need arises, compared with 40 percent who say she's qualified.

By contrast, 64 percent believe Biden is qualified to be president, versus just 21 percent who disagree.
