The poll showed support for Clinton at 44 percent while Sanders stood at 42 percent. This represents no change from the results of Quinnipiac’s previous national poll, carried out earlier in the month.
Most national polling, however, has tended to show a wider gulf between the two candidates even as Clinton's lead has narrowed. TPM’s PollTracker Average shows Clinton in the lead at 46.2 percent compared to Sanders’ 41 percent.
The Quinnipiac poll was conducted by live phone interviews from Feb. 10-15. The sample population of likely Democratic voters was 563 with a margin of error of 4.1 percentage points.
