Former Vice President Al Gore hit the campaign trail for Hillary Clinton on Tuesday, in an attempt to inspire millennials to get out and vote for the Democratic nominee.
But wait -- do millennials even know who Al Gore is?
There aren't any scientific polls out there about this, but we sent reporters to interview young people on the street in Florida and Washington, D.C. -- and for the most part, people didn't seem to know much about the 68-year-old environmentalist and climate change activist.
Watch | We asked millennials if they know who Al Gore is. Some had no idea. And most others, even if they knew who he was, didn't know a ton of facts about him.
'A perplexing surrogate"
Pundits across the internet have questioned Clinton's choice of Gore as a surrogate for younger voters.
"As a personality, Gore is a perplexing surrogate for millennial outreach," Graham Vyse wrote in The New Republic on Tuesday. "Analysts are rightly skeptical about how relatable a 68-year-old can be in this role, especially one whose last big cultural contribution was a documentary released a decade ago."
Getting the climate vote
Others, however, have pointed out that Gore's role may be less for millennials in general and more for millennials who are specifically concerned about climate change.
Strictly anecdotally, most of the young people we spoke to on the streets of D.C. and Florida didn't know that Gore was a former vice president, and didn't know much about his presidential campaign against George W. Bush.
But the ones who did know him knew about his status as a climate activist, and his documentary, "An Inconvenient Truth."
If Gore is indeed well-known among millennials for his climate activism, that could be beneficial for Clinton, as polls show young voters more likely than older voters to list climate change as a core issue.
A recent poll from NextGen Climate, for example, showed that 76 percent of millennial voters in swing states were more likely to support a candidate who supports limiting carbon emissions from power plants.
The poll also showed 83 percent of swing state millennials more likely to vote for a candidate who supports transitioning away from fossil fuels and toward renewable energy.
