Support for Clinton among some of her traditionally stalwart support groups -- women, Easterners, whites, adults with no college education, and Hispanics -- has fallen below 50%.
The only major demographic group still supporting Clinton to the tune of 51% or more is women aged 50 and older. This group's preferences have changed little during May, at the same time that Clinton's support among younger men (those 18 to 49) has declined by nearly 10 points.
