Last week, a CBS News / New York Times Poll showed that the Democratic race for the presidential nomination may be tightening. It had Hillary Clinton with only a 7 point lead over Bernie Sanders -- far closer than other polls have shown.
But that poll could be an outlier, because two new polls show Clinton with a much larger lead nationally. Both of them have Clinton with a 25 point lead nationally over Bernie Sanders.
The first is the NBC News / Wall Street Journal Poll -- done between January 9th and 13th of a random national sample of 400 Democratic primary voters, with a margin of error of 4.9 points.
The second is the latest YouGov Poll -- done between January 9th and 11th of a random national sample of 620 Democratic primary voters, with a margin of error of 4.2 points.
