Bernie Sanders says his razor-thin contest against Hillary Clinton in Iowa is giving his campaign a "kick-start."

The Democratic presidential candidate says it shows the American people that "this is a campaign that can win."

Sanders tells reporters traveling aboard his flight to New Hampshire early Tuesday that his message of addressing wealth inequality resonated with voters in Iowa. He predicts it will resonate in the early voting states of New Hampshire, Nevada and South Carolina.

"Together, we are going to create an economy that works for working families and not just the 1-percent," Sanders said during an event in Manchester, New Hampshire on Tuesday. 

Polls show the Vermont senator leading Clinton in New Hampshire. But Sanders isn’t saying whether he considers anything less than victory there a successful outcome. He says his campaign is in it "for the long haul" and predicts that "we are going to win some states, we are going to lose some states."
