With just five days to go until the public ballot closes, both Def Leppard and Stevie Nicks look set to sweep the fan vote for induction into the Rock & Roll Hall of Fame in 2019.

The poll opened in October, and consists of 15 nominees that represent a number of genres beyond merely rock. Over three million votes have been cast at time of writing, with the pair having taken an early lead that they have consistently held.

Def Leppard are currently storming ahead, with Joe Elliott and co having already secured in excess of 500,000 votes. Fleetwood Mac vocalist Nicks is the most likely runner up with over 400,000 votes, while Todd Rundgen follows her with more than 333,000.

The remaining nominees consist of The Zombies, The Cure, Janet Jackson, Devo, Roxy Music, Rage Against the Machine, Radiohead, John Prine, LL Cool J, Rufus & Chaka Khan, Kraftwerk and MC5 in order of votes.

Inductees are decided by a combination of the fan vote with the votes of associates of the Hall of Fame in the shape of varying performers, writers and executives. It's a good omen for the current leaders, as since the inception of the fan vote in 2012, all winners have gone on to be inducted.

When conducting an interview with Loudwire, Elliott discussed the possibility of being inducted, and name-checked Nick as being worthy of entering the exalted hall alongside Def Leppard.

“Stevie Nicks, from a commercial point of view, [has] had an astonishingly long career in and out of Fleetwood Mac," he told the publication. "You can't deny that she's earned the nomination."

The rock legends fronted by Elliott proved that they still haven't missed a step in rocking Dublin's 3Arena last week, which kick started their relatively short but extensive tour of the UK and Ireland that culminates on the 18th of this month at the SSE Arena in Wembley.

There's still time to make doubly sure that they come out on top of the poll by heading over to the Rock & Roll Hall of Fame's website and voting yourself. Fans can vote once per day, every day until the ballot closes at the end of the 9th of December.
