PRINCETON, NJ -- There is little change in the latest Gallup Poll Daily tracking update on the contest for the Democratic presidential nomination, with support among national Democrats at 49% for Barack Obama and 46% for Hillary Clinton. (To view the complete trend since Jan. 3, 2008, click here.)
Both Democratic candidates are hard at work campaigning in Pennsylvania, which holds its primary on April 22, and in North Carolina and Indiana, whose primaries are on May 6. The biggest news surrounding the Democratic campaign continues to be the focus on the ultimate endgame, and the implications for next fall's general election of a close and contested race that could last through the summer.
The latest update on general election preferences shows Republican John McCain with a two percentage point advantage over both Democrats among registered voters -- 46% to 44% versus Obama and 47% to 45% versus Clinton. These standings of the candidates are unchanged from Tuesday's report. -- Frank Newport
