Two years away from the 2020 New Hampshire presidential primary, most Democratic primary voters are still trying to make up their minds on which candidate to support, but Joe Biden, Bernie Sanders, and Elizabeth Warren remain the early frontrunners. After receiving the second most support last October, Biden has now taken the lead over Sanders. Most Republicans are still trying to decide whom to support, but six in ten say they plan to vote for Trump in the 2020 primary, an increase since October and comparable to the proportion of Democrats who planned on voting for Barack Obama in February 2010. Interest in the 2020 primary has increased since October and is considerably greater than at this point in the last two electoral cycles.
