From NBC's Mark Murray
Earlier today, Howard Wolfson, the communications director for Hillary Clinton's presidential campaign, said in a memo: "As [Clinton strategist] Mark Penn likes to say, people always ask 'can Hillary win?' but he has never had this asked of someone who is already winning. This week's national polls underscore that observation."
But those polls only tell part of the story. According to a new Mason-Dixon survey, given exclusively to NBC/MSNBC and McClatchy newspapers, Clinton is the only major presidential candidate -- either Democrat and Republican -- for whom a majority of likely general election voters say they would not consider voting. In addition, she's the only candidate who registers with a net-unfavorable rating.
In the poll, 48% say they would consider voting for Clinton versus 52% who say they wouldn't. By comparison, majorities signal they would consider voting for all other major presidential candidates or possible candidates: Giuliani (64%-36%), Fred Thompson (62%-38%), Bloomberg (61%-39%), Obama (60%-40%), Edwards (59%-41%), McCain (58%-42%), Biden (57%-43%), Richardson (57%-43%), Huckabee (56%-44%), and Romney (54%-46%).
Moreover, 39% say they recognize Clinton favorably, while 42% say they recognize her unfavorably. By contrast, every other candidate has a net-positive favorable rating: Giuliani (43%-17%), Obama (36%-21%), McCain (33%-28%), Edwards (32%-28%), Thompson (25%-12%), Romney (24%-20%), Biden (21%-20), Bloomberg (20%-18%), Richardson (19%-15%), and Huckabee (16%-12%).
The poll was taken of 625 likely general election voters from June 23-25, and has a margin of error of +/- 4%.
