As we know, national polls of presidential primary candidates aren't meaningful as far as actual state primary results, but they shape coverage, perception of viability, and often fundraising.
Washington Post/ABC News Poll, 1/16-1/19, MoE 3%, (12/11).
Democrats, including leaners:
Hillary Clinton 41 (39)
Barack Obama 17 (17)
John Edwards 11 (12)
Al Gore 10 (10)
John Kerry 8 (7)
Republicans, including leaners:
Rudy Giuliani 34 (34)
John McCain 27 (26)
Mitt Romney 9 (5)
Newt Gingrich 9 (12)
Head to head matchups, with the following caveat from kos:
Head-to-head polls invariably lead to those idiotic debates about who is more "electable". But this early, these sorts of polls are more a gauge of name recognition and latent popularity than the decisions based on year-long presidential campaigns. So I like the numbers as a baseline, but they have no bearing on the ultimate "electability" of any of these candidates. (And yeah, some of you will still make that argument as you promote your favorite, and there's nothing I can do about it.)
So this poll has things looking very stable over the past month. It was done just as Obama announced, and finds no bounce for him from that. Clinton, not having announced as the poll was done, edged up but within the margin of error. She obviously continues to benefit from name recognition, as her favorable-unfavorable ratings show: 54% favorable, 44% unfavorable, with only 3% with no opinion while Giuliani, McCain, and Obama all have "no opinion" responses in double digits. Only Giuliani has higher favorables, at 61%, and no one else's unfavorables are as high - McCain is second at 35%. As the name recognition factor diminishes, the picture will probably change.
