Reply #30: 9/27/07 - Clinton slightly down, Obama up, Edwards down

But still no real long-term trends. I thought doing this graph would be exciting, but not only is it the opposite of encouraging for an Edwards supporter, it's also surprisingly boring. Perhaps it's true that most voters still aren't paying a lot of attention. Or that their minds are pretty firmly made up. For now, anyway.

Rasmussen doesn't say when the daily numbers were collected. The numbers dated 9/27 obviously are from 9/26 at the latest, and maybe from 9/25 or 9/24. That makes it hard to know when to look for an effect, if any, from a particular event, such as a debate or an announcement.
