This was a serious, credible argument. But in November 2010, Democrats won only 38% of the white vote. Taking into account exit polls, the National Election Study and historic popular vote totals, it was probably the worst showing among whites, at least as presently defined, for any major party dating back to 1822. Two years later, in a more favorable environment, Democrats still managed only 40% of the white vote.
Sorry. No data so far.
