Hillary Clinton holds just a two-point lead over Vermont Sen. Bernie Sanders nationally in the Democratic presidential race, a new poll shows.

An NBC News/Wall Street Journal survey released Monday has Clinton at 50% support to Sanders’ 48% — down from Clinton’s nine-point advantage in the same poll one month ago.

Since more than half of all Democratic voters have already taken part in their states’ contests, the national numbers are a limited gauge of where the race stands.

New York is set to hold a key primary on Tuesday, and Clinton is favored by a larger margin there, giving her an opportunity to build her lead among both delegates and in the popular vote.

A Sanders win in New York, though, could shift the tide of the race before five East Coast states vote the following week.

The national poll found Clinton with a 15-point advantage among women, 57% to 42% — down from a 20-point lead earlier this year. Sanders leads among men, 58% to 41%.

Clinton also leads among minority voters, 59% to 41%, a decline from her 30-point advantage in previous NBC News/Wall Street Journal polls.

Clinton’s strongest group is those 50 and older. With them, she leads 62% to 35%. Sanders, meanwhile, is up 66% to 34% among those ages 18 to 49.

The survey of 339 Democratic primary voters nationally was conducted April 10-14, and includes a margin of error of plus or minus 5.3 percentage points.
