"This is what I say to my rural voters: I say look at what’s in front of you, because for too long we’ve been talking about it as more of a coastal issue," Klobuchar said.

"Let’s talk about it for the middle of the country, where we need the political support," she continued. "And I personally think someone from the Heartland could do a pretty good job of that."

The joke, which drew laughs from the audience at Saint Anselm College in New Hampshire, appeared to be a reference to a 2016 presidential debate between Hillary Clinton Hillary Diane Rodham ClintonDemocratic groups using Bloomberg money to launch M in Spanish language ads in Florida The Hill's Campaign Report: Presidential polls tighten weeks out from Election Day More than 50 Latino faith leaders endorse Biden MORE and then-candidate Donald Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'
