Two pillars of the Democratic coalition, African-Americans and young voters, show marked declines in interest, a potential problem for Hillary Clinton in her contest against Donald Trump.
Some 65% of African-Americans rate themselves as highly interested in the election, down 18 points from the 2012 election and down 28 points from 2008, the Journal/NBC News survey found.
Only 54% of younger voters, those under age 35, say they have high interest in the election, down 6 points from the 2012 election and nearly 30 points from 2008.
In good news for Mrs. Clinton, Hispanic voters appear to be engaged. Some 69% of Hispanic voters rate themselves as highly interested in the campaign, up 1 point from 2012 and nearly equal to the electorate overall.
