Sen. Bernie Sanders (I-VT) has a lead of two percentage points over former Secretary of State Hillary Clinton among Democrats nationwide, while one in four of his supporters do not plan on supporting Clinton if she wins the nomination, according to a McClatchy-Marist poll released Wednesday.

The poll showed support for Sanders at 49 percent while Clinton stood at 47 percent. Furthermore, 25 percent of Sanders supporters said they would not support Clinton as the Democratic nominee in the general election, while only 14 percent of Clinton supporters said the same of Sanders.

This is the first McClatchy-Marist poll of Democrats nationwide, and it contrasts sharply with recent polling, nearly all of which shows Clinton enjoying a comfortable lead. TPM’s PollTracker Average shows Clinton at 47.4 percent, and Sanders at 42.5 percent.

The McClatchy-Marist poll was carried out from March 29-31 using live phone interviews. Pollsters surveyed 444 people likely to vote in the Democratic primary, with a margin of error of 4.7 percentage points.
