A few weeks ago I pointed out "the Democratic electorate is older, more moderate and less educated than you think". Age: Biden's up 30% to 19% over Sanders among Democrats under the age of 50. Among those age 50 and older, Biden holds an astounding 48% to 11% over Sanders. He holds an over 30 point advantage among moderate and conservative Democrats. Education: Biden is up just 11 points among Democrats with a college degree.
