The National Primary

Look at the steady evaporation of Clinton's lead since January 20:

Money quote:

Clinton's lead in the three-day average is now 42% to Obama's 36%. John Edwards, who dropped out of the race Wednesday after Gallup conducted these interviews, ended his quest for the presidency with 12% support. Wednesday night's interviewing will reflect the distribution of the vote choice of former Edwards' supporters as well as the impact, if any, of Hillary Clinton's popular vote win in Florida on Tuesday.

These national numbers are a critically important indicator of the political environment when voters in more than 20 states go to the polls next Tuesday. At the moment, Obama has the momentum among Democrats nationally.
