The poll released Friday finds Clinton leading the race with 44 percent support, compared to 42 percent support for Sanders, within the survey’s margin of error.
The last iteration of the poll in December had Clinton leading Sanders nationwide by a 61-30 point margin.

“Democrats nationwide are feeling the Bern as Sen. Bernie Sanders closes a 31-point gap to tie Secretary Hillary Clinton,” said Tim Malloy, assistant director of the Quinnipiac University Poll.

The poll also finds that Sanders matches up better with top Republican primary candidates than Clinton.
