Hill.TV poll finds Dems hold 30-point lead over GOP among millennials

Democrats beat Republicans by 30 points among millennials on the generic ballot, according to a new American Barometer survey. 

The poll, conducted by Hill.TV and the HarrisX polling company, found that 53 percent of 18- to 34-year-olds surveyed said they would support a Democratic candidate in November's midterm elections, while 26 percent said they would support a Republican candidate in their district. 

The survey comes as parties and organizations aim to encourage younger adults to vote in the midterms. 

"There's been tremendous effort put forward to turn out that millennial vote. So a lot of money is being spent, a lot of effort is being expended to make sure that those millennials voter," Democratic pollster Mark Mellman told Hill.TV's Joe Concha on "What America's Thinking." 

Musician Taylor Swift Sunday targeted her younger-skewing fanbase when she broke her career-long political silence and endorsed two Tennessee Democrats ahead of the midterms. 

Swift continued her political messaging at the American Music Awards on Tuesday, encouraging her fans to "get out and vote" on Nov. 6. 

Vote.org revealed earlier this week that it witnessed a flood of new voter registrations since Swift broke her silence on politics. 

"We just saw Taylor Swift the other day register a lot of people just by saying it was important, and you're going to have a lot of folks I think telling those millennials that it's important for them to get out and vote," Mellman continued. 

The American Barometer poll was conducted Oct. 6-7 among 1,000 registered voters. The sampling margin of error is plus or minus 3.1 percentage points.
