Democrats could get a boost during the 2018 midterm elections from historic young voter turnout, according to a new poll.

About 1-in-3 young people are "extremely likely" to vote as part of November's midterm cycle, a Center for Information and Research on Civic Learning and Engagement survey released Tuesday found. That rate is similar to the one the center recorded in a previous poll conducted ahead of the 2016 presidential election when two-fifths of 18 to 24-year-olds indicated the same likelihood of casting a ballot.

The surge, unusual for midterm elections, favors Democratic congressional candidates. This is because the center's study also found 45 percent of young people would vote for a Democratic House candidate as opposed to just more than 25 percent who would support a Republican vying for a congressional seat.

The upward trend appears to be driven by 18 to 21-year-olds who weren't eligible to vote in 2016, according to the poll. Many of those young people have been inspired to participate in the political process by the latest anti-gun movement sparked by February's high school shooting in Parkland, Fla.

The Center for Information and Research on Civic Learning and Engagement, which is affiliated with Tufts University, surveyed 2,087 people aged 18 to 24 between Sept. 5-26. Its findings have a margin of error of 2.1 percentage points.
