Ernst leading by 1 in PPP's pushiest pull is a good sign for her.
They asked the horserace question before all that other stuff (actually the only question that came before the horserace one was how likely people were to vote). I don't think these numbers are a good sign for Ernst (although it's obviously better to be ahead then behind). If anything, this poll suggests that the race is close enough that a strong ground-game could allow Braley to pull off a narrow win. What worries me is the Des Moines Register poll. Someone's going to have egg on their face Wednesday morning.
