Democratic Party still bleeding White voters?

[Ebsy]

It's possible that Democrats could continue to shed white voters in midterm years, though it's hard to imagine exactly where it has left to shed them outside of white liberals who I have a hard time seeing voting for Republicans. But in presidential election years for the past 30 years, Democratic share of the white vote has fluctuated above and below 40%. Some candidates do substantially better, some do much worse, but there isn't really much of a trend. Perhaps one could exert itself in the future, but there isn't any data now that suggests Democrats are going to drop to say 30% of the white vote.
