Bernie Sanders is headed back to New Hampshire.

The Vermont independent is set to headline two Labor Day events in the Granite State over the upcoming weekend, a move that has some wondering whether he's considering another run for the Democratic Party's presidential nomination in 2020.

Sanders' trounced Hillary Clinton during the New Hampshire primary in 2016, earning more than 60 percent of the vote to her 38.

The senator's fanatical supporters have inflamed intra-party tensions between hardcore progressives and establishment Democrats, rippling into the race for DNC chair earlier this year, and continuing to amplify divisions. There's an effort afoot to "draft" Sanders for a so-called "People's Party" to run against both Republicans and Democrats.

Along with Joe Biden and Sen. Elizabeth Warren, D-Mass., Sanders is also one of three potential Democratic candidates who would be in their seventies come election day.

Persistent enthusiasm for his radical platform is a problem for Democrats scrambling to rebuild the party after a decade of disastrous down ballot loses. He's also not afraid to challenge DNC leadership, creating headaches for establishment leaders struggling to present a united front against President Trump and the GOP. The senator's anti-establishment bent only compounds the party's efforts to rebuild trust between its grassroots and leadership and craft a message that resonates both with working class voters and progressives who demand purity.

So long as Sanders maintains an elevated profile in the party, Democrats will struggle to unite.
