Among those who have voted or plan to vote in a Democratic contest this year, Sanders has 49 percent support to Clinton's 48 percent, a Bloomberg Politics poll found.
It's just the second national poll of the cycle finding Sanders ahead of Clinton, along with a Fox News poll in February that had him up by 3 points. Clinton has led several recent polls by double digits.
Clinton has won 1,223 pledged delegates, along with the support of 467 superdelegates, according to the Associated Press delegate tracker. Sanders has 946 delegates and 26 superdelegates.
But hundreds of superdelegates have not yet picked a side, and those that have are free to switch at any point before the official convention vote.
Sanders also does better in head-to-head match ups against the Republican presidential candidates, although both Democrats have strong numbers.
