Well, it seemed just a few days ago that Obama was forging a significant 8 - 10 point lead in both national tracking polls. Now that is gone. Rasmussen now has Obama down one point (46-45) and down 50-42 to McCain (he was up 2 a few days ago). And most of that data was before the recent overblown "bitter" story getting widespread media attention.
Similarly, we have Gallup. Now their tracking poll is not out yet, but yesterday his lead had shrunk, and they ominously stated:
The latest results are based on interviews with national Democratic primary voters conducted April 9-11 and represent Obama's sixth straight day of leading Clinton by a significant margin in Gallup Poll Daily tracking reports. Obama's lead is substantially narrower in the two most recent days of interviews, however, suggesting the race could tighten in the coming days.
Look for Gallup to be a toss up again today. By Wednesday, Obama could trail by 5 points or more in both polls. This is not where this race needs to be. If he was up 10 points, and Pennsylvania showed him down by 8, where will he be this week in Pennsylvania? Or on April 22? I shudder to think.
