When asked on CNN's "State of the Union" how he will appeal to black voters, the Vermont senator said his campaign is seeing "not just a racial divide, but a generational divide."

"We are doing better and better with younger people, whether they're black, Latino or white," he said.

"Our numbers are getting better and better. In general, our numbers are getting better."

Sanders admitted his campaign hasn't done well in the deep South, but he said he's confident his numbers will continue to go up.

"And what we have done, based on yesterday at this point, we have now won seven primaries and caucuses all across this country, all with double-digit victories," he said.

He added that if the turnout is high in Maine on Sunday, he thinks he has a good chance of winning there.

"Just kind of showing strength all across this country," he said.
