Kwin-uh-PEE-ACK! Clinton pollsters. Always oversampling Democrats. Typically, a 5-7% oversampling of Democrats. I looked at the .pdf and there’s no mention of Dem/Rep/Ind sampling to check for bias.
Also, pay attention to the fact this poll is “registered” voters, not “likely” voters.
And how many are “registered”, but registered somewhere else, like New Yawk, Haiti, Venezuela, etc.?
