Clinton and Obama Tied?

Most folks thought the last Democratic debate was a draw, but the daily Gallup polls seem to show otherwise. According to Gallup, Obama and Clinton are now running neck and neck. The latest poll gives Hillary a one-point lead, marking the first time Obama has not led in Gallup's daily tracking since March 18-20.

I'm a bit surprised by this. It will be interesting to see how Pennsylvania votes on Tuesday.
