Bernie Sanders and Joe Biden continue to be early frontrunners for the 2020 New Hampshire presidential primary, although most Democratic primary voters are still trying to make up their minds who to support. Most Republicans are also trying to decide who to support, but just over half say they plan to vote for Trump in the 2020 primary. Two-thirds of Republican primary voters would vote for Trump in a hypothetical matchup with Ohio Governor John Kasich.
