Poll: Clinton leads Sanders by 15 in Pa.

Democratic presidential front-runner Hillary Clinton holds a big lead over rival Bernie Sanders in Pennsylvania just days before the state’s April 26 primary, according to a new Wall Street Journal/Marist/NBC poll.

{mosads}Among likely Democratic voters, Clinton has 55 percent support to Sanders’s 40 percent.

She has over 60 percent support among African-Americans, voters over 45, women and voters who identify as Democrats.

But the Vermont senator continues to dominate among younger voters, with 60 percent of those under 45 supporting him.

Both candidates beat Republican front-runner Donald Trump in a hypothetical general election match-up. Clinton leads the business mogul 54 to 39 percent, while Sanders tops him 57 to 37 percent.

The poll surveyed 734 likely Democratic primary voters from April 18 to 20. It has a margin of error of 3.6 percentage points.

Clinton’s lead over Sanders is just 8 points, however, in a CBS News Battleground Tracker poll released early Sunday.
