Election analyst says GOP-leaning independents could help 2020 Dems

Many GOP-leaning independents will likely support a Democratic candidate during the 2020 presidential primary season, polling and election analyst Henry Olsen said Wednesday.

"Republican-leaning independents, when they're faced with that choice, a lot of them presumably don't like the president, they will have the choice to vote in a Democratic primary to select someone who could beat the president," Olsen told Hill.TV's Joe Concha on "What America's Thinking."

Fifteen states have open primaries, according to the National Conference of State Legislatures.

"Or they could participate in a Republican primary and throw their vote away for someone who's not going to beat the president," Olsen added.

His comments come amid talk of whether a Republican will challenge Trump in the primary.

The Democratic field is expected to be a crowded one. Sen.

"So I think a lot of those Republican-leaning independents, who say, 'Well, I'd like to have another Republican,' will in fact vote in the Democratic primary, just as they voted Democratic for the House this time," he said.
