I can think of ev for all three, to some extent or another. --We know design/questions effect answers (see voter file v. our poll!) --The Hisp. question could be subject to acquiescence bias --We know response rates vary by race --We know the CPS is high on southern turnout — PolitiTweet.org

This raises (at least) a few possibilities: --our poll is biased v. IRL pop. We get too many Hispanics, for ex. --our design/format leads to bias v census. Here, we have right respondents but they respond differently in this setting --CPS turnout way overshoots black turnout/reg — PolitiTweet.org

On the question of whether our *respondents* are biased, one test is to look at the respondents who said they were black on their voter registration form, but not in our survey. They still vote overwhelmingly Democratic, which to me says our sample is probably unbiased — PolitiTweet.org
