Senator Bernie Sanders, I-Vt., has seen a significant jump in support in a new CBS News/New York Times poll and now trails Democratic presidential frontrunner Hillary Clinton by just single digits.

The poll found that 48 percent of Democratic primary voters support Clinton, while 41 percent said they favor Sanders.

Clinton's seven-point lead in the latest poll is substantially narrower than the 52 percent to 32 percent advantage she had over Sanders last month.

Sanders has benefited from a significant increase in support among younger voters and liberals, while Clinton continues to lead among women, moderates, and voters over age 45.

The national poll results come on the heels of separate surveys showing Sanders leading in the key early voting states of Iowa and New Hampshire.

A Quinnipiac University poll showed that Sanders has jumped into the lead in the first-in-the nation caucus state of Iowa.

The poll showed Sanders with a 49 percent to 44 percent lead over Clinton in Iowa, while a poll conducted last month showed Clinton with a 51 percent to 40 percent advantage.

A separate Monmouth University poll showed Sanders with a 53 percent to 39 percent advantage over Clinton in New Hampshire's first-in-the-nation primary.

However, Clinton dismissed the polls in an interview with NBC's "Today" show on Wednesday and said she was not nervous about the jump in support for Sanders.

"I'm working hard, and I intend to keep working as hard as I can until the last vote or caucus-goer expresses an opinion," Clinton said. "I'm excited about where we are."

Clinton indicated she would focus on highlighting the differences between her and Sanders and recently released an ad challenging the Senator to "pick a side" on gun control.

The CBS/NYT survey of 389 Democratic primary voters was conducted January 7th through 10th and has a margin of error of plus or minus 6 percentage points.
