Pollster says likely Dem 2020 nominee has not emerged in national conversation yet

Pollster Lee Miringoff said Friday that the likely 2020 Democratic nominee has not yet emerged in the national conservation.

"The person we're going to be talking about in four or five months or six months, eight months, may not be on anyone's radar," Miringoff, director of the Marist poll, told Hill.TV's Jamal Simmons on "What America's Thinking." 

"Right now, [Sen. Bernie] Sanders [I-Vt.], [former Vice President] Biden, three or four others, known entities. Everybody else [is] kind of off the radar," he continued. 

"I think we're likely to see someone emerge who can take it wire to wire," he said.

A CNN poll released Friday found that 30 percent of voters said they supported Biden as a potential 2020 contender, while 14 percent said the same for Sanders. O'Rourke, meanwhile, doubled his support in the poll from a similar poll released in early October.
