More statistical ignorance from here.
In a 2015 YouGov survey, respondents reckoned that 32 percent of Democrats are LGBT, 29 percent are atheists or agnostics, and 39 percent belong to unions; the right figures are really 6, 9, and 11 percent, respectively. Meanwhile, they estimated that 38 percent of Republicans earn over $250,000 per year, 39 percent are over age 65, and 42 percent are evangelicals; actually, just 2 percent earn that much, 21 percent are senior citizens, and 34 percent are evangelicals.
Look how far off people's beliefs are from reality.
