That should be expected. Party identification has long been the most important determinant of Americans’ vote choices for president. Partisanship is so powerful, in fact, that in a Huffington Post/YouGov survey taken last week, 58 percent of Republicans agreed that “the worst member of the Republican Party is still better than the best member of the Democratic Party.”

Along with partisanship, there’s another factor that could minimize the impact of sexual assault allegations against Donald Trump: Republicans in general, and Trump’s primary voters in particular, were already more skeptical of women who accuse men of sexual harassment.
