Former Vice President Al Gore’s supporters have started chatting with him about a potential 2016 presidential bid, The Hill reported Thursday, citing BuzzFeed News.

“They’re figuring out if there’s a path financially and politically,” a Democratic source told the website, which noted Gore hasn’t made any moves toward running.

“It feels more real than it has in the past months,” said the source.

The report gained further traction later on Thursday, when ABC’s Rick Klein tweeted that a former Gore adviser confirmed that a “circle of his former aides are talking about” a potential 2016 bid, though they are still in the very early part of the discussion.

Gore, who served as vice president to Bill Clinton, was the Democratic presidential nominee and won the popular vote during the 2000 election to George W. Bush, though he lost the election.

Gore has since focused mostly on environmental activism, with little to no signs he is interested in another White House bid.

The leading Democratic candidate is former Secretary of State Hillary Clinton, though The Hill noted that her primary rival, Sen. Bernie Sanders (I-VT), surged ahead of her in a New Hampshire poll released this week.

Another candidate in the Democratic race is former Rhode Island Governor Lincoln Chafee, who has cast himself as an anti-war candidate who opposed the invasion of Iraq back when Clinton supported it. Current Vice President Joe Biden has also been rumored to be considering a presidential run.

A request for comment from Gore’s office by The Hill was not immediately returned.
