I don't think this has been diarized yet. From Susan Page, of USA Today
(February 12, 2008) — WASHINGTON — Democratic presidential hopeful Barack Obama has edged ahead of Hillary Rodham Clinton for the first time in a nationwide USA Today/Gallup Poll, which also shows Republican John McCain struggling to energize a dispirited GOP.
A different poll shows Clinton still ahead of Obama, however.
The surveys were released on the eve of primaries today in Virginia, Maryland and the District of Columbia. In both polls, McCain is running statistically even in a head-to-head contest against Clinton and slightly behind Obama.
In the USA Today poll, Obama bests Clinton 47 to 44 percent among Democrats and independents who lean Democratic.
Among Republicans, McCain leads Mike Huckabee 53 to 27 percent among Republicans and independents who lean Republican. The poll of 1,016 adults has a margin of error of plus or minus 3 percentage points for the full sample and plus or minus 5 points for the Republican and Democratic subsamples.
The other poll released Monday, by the Associated Press-Ipsos, differed, showing Clinton leading Obama in the race for the Democratic nomination, 46 to 41 percent. [sic--see below]
The AP-Ipsos survey of 1,029 adults was done Feb. 7-10. It had an overall margin of error of plus or minus 3.1 percentage points.
The previous results for this poll can be found here. The article says yesterday's AP/Ipsos poll contradicts it, but it looks like that's an error. Dunno what to say...
