Hmmm, I wonder if he’s running.

Via WaPo:

Major Democratic fundraisers have been invited to meet with Vice President Joe Biden at his residence at the U.S. Naval Observatory after Labor Day, part of a series of conversations he is having with senior party players as he contemplates jumping into the 2016 race.

Among the guests invited to the gathering are top bundlers who raised large sums for the Obama-Biden campaigns in 2008 and 2012, according to people familiar with the outreach. The sitdown is scheduled to take place during the week following Labor Day.

Biden’s office declined to comment.

In recent weeks, Biden has been huddling with longtime supporters and allies to discuss the possibility of making another White House run. On Saturday, he met with Elizabeth Warren, the populist senator from Massachusetts.

His consideration of another campaign comes as front-runner Hillary Rodham Clinton has fielded mounting questions about her use of a private email server while she was secretary of state.
