The Burnt Orange Report has asked IVR Polls to do a monthly tracking poll on the Democratic presidential primary race for Texas. For the time being, these polls will assume the primary will not move to February. As such, we will poll past primary voters. We'll change the model if the primary move to February becomes more certain. While this poll listed all eight candidates, future tracking polls will only list the top four, then 'Other.' Lengthy questions increase the hangup rate, introducing bias. A followup question about second choices had an obvious hangup pattern, so we are not reporting those results. Maybe next time with the shorter list.

Timing on the poll was interesting for two reasons. First, it was done the day of Elizabeth Edwards' news. Second, it was done the day before the American Research Group released their poll on the race. In the first case, the attention may have given John Edward's numbers a boost. He was up four points from my poll last month, while both Clinton and Obama were down.

The second case gives an excellent opportunity to compare poll results from different methodologies. I'll get into those details after the jump.
