WASHINGTON — Bernie Sanders is only 6 percentage points behind Hillary Clinton nationally, as the Democratic race continues to tighten.

A new CBS News/New York Times survey shows Clinton with a 47% to 41% lead over Sanders, a decrease from what was a 20 percentage-point gap only a month ago, when Clinton led 52% to 32%. The national poll follows other polls that show what appears to be a surging Sanders in both Iowa and New Hampshire.

The uptick for Sanders nationally comes almost entirely from younger voters: Sanders is up 60% to 31% with Democrats under the age of 45, compared with a 48% to 41% margin in his favor in December.

Among Republicans, the story remains the same: Donald Trump is trouncing the rest of the field nationally.

Trump leads with 36% support, according to the Tuesday survey, leading Ted Cruz with 19%. Following Cruz is Marco Rubio at 12%, Ben Carson at 6% and Jeb Bush also at 6%. All other candidates have less than 5%.

And on the evening of the State of the Union address, those polled by CBS News/New York Times are evenly split on President Barack Obama: 46% say they approve of him, and 47% say they disapprove.

The margin of error for both the Democratic and Republican races is 6 percentage points.
