Normally, I would agree with you. However, I think Rasussen has gotten a couple days of bad samples. He matches Gallup, NBC, and Pew. They only use adults and he uses LV, there is no way they can come out the same. I think Zogby is close on this one. I expect Rasmussen to follow suit in the next few days.
Gallup 8/17 - 8/19 1547 A 51 42
Rasmussen Reports 8/17 - 8/19 1500 LV 50 50
NBC News 8/15 - 8/17 805 A 51 40
Pew Research 8/11 - 8/17 2010 A 51 37
For note, you’re just hearing the skeptic in my brain who was burned on Zogby before. He could be right, but I just like being very careful on this.
