A new NBC/WSJ poll found 72% of Democratic voters have a high interest in voting in the midterms, compared to 68% of Republicans. In 2014, only 47% of Democrats and 59% of Republicans felt similarly.

The big picture: Interest in voting has increased by double digits among Latinos, young voters, and women ahead of the election, compared to their average in previous NBC/WSJ polls throughout the year. Those are crucial voting blocs for Democrats and could decide the election if they actually show up on Nov. 6.

By the numbers: Democrats lead the generic congressional ballot by nine points, which is lower than the double digits they've seen in earlier polls.

• Voters trust Democrats more on health care (they lead by 18), but look to the GOP on the economy (they lead by 15).
• Republicans are up by eight among white women without college degrees. But Democrats lead by 29 on the issue of which party is looking out for “women’s interests.”
