The inner city public school systems. These are people that believe facts should come secondary to feelings. Remember the 2000 Florida voting debacle. There were people who claimed they were confused by the ballot, never mind that they tested that ballot on third graders after wards and they could figure it out, and believed they should have the right to re vote. Not in 2004, but then. Now, if you screw up a ballot, in a normal world you would have to wait till the next election and be more careful. That's the law. However, these are the same people who thought their feelings should override the rule of law.
You're seeing the same thing here
IIRC, the "confused" voters were older Jews and other liberals, who a phone bank's calls convinced that they might have accidentally voted for Pat Buchanan!
