If you haven't seen already, PPP's last Iowa poll shows Ernst leading Braley by 3, a bit of a difference from their October 16th poll that had Braley leading by 1. So where did this 4 point shift come from? Well, in their October 16th poll, Ernst led Braley with white voters by only 2 points, which would probably be good enough for Braley to win even though whites are 90+% of the electorate in Iowa. In their latest poll, however, Ernst ups her lead with whites to a monstrous... 2 points... What the heck? How can Ernst have the same lead with whites, but improve a whopping 4 points overall?!? Well, in the October 16th poll Braley leads with non-whites by 19 points, while in the latest poll Ernst leads with non-whites by an absurd 10 points. I guess Latinos and African Americans and Asians really love them some Joni Ernst. As Wayne Campbell might say, yeah, and monkeys could fly out of my butt! This just highlights pollsters inability to accurately poll non-white voters. In Iowa, the electorate is probably 2-3% African American, 2-3% Latino, and 1-2% other. There is no way in heck Braley is winning non-white voters by fewer than 20 points, and it's probably much more. To make a long story short, if Ernst only wins white voters by 2 points, as is shown in both of these polls, she will lose easily.
