From Pew:
Americans are far more likely to say there are strong conflicts between Democrats and Republicans in U.S. society today than to say the same thing about blacks and whites, the rich and the poor, and other social groups.
An overwhelming majority (86%) of Americans say conflicts between Democrats and Republicans are either strong or very strong, according to a new Pew Research Center survey. By comparison, 65% of Americans see strong or very strong conflicts between blacks and whites, and 60% see them between the rich and the poor.
