Bernie Sanders claims momentum over Hillary Clinton after 3 easy caucus wins

Bernie Sanders says his three latest wins over Hillary Clinton should persuade people -- and delegates -- to re-think the Democratic presidential race.

"Clearly we have the momentum," Sanders said on ABC's This Week. "And I think at the end of the day we’re going to end up with more pledged delegates than Secretary Clinton."

Sanders has a long way to go.

While the Vermont senator easily won Saturday caucuses in Alaska, Hawaii, and Washington, Clinton still leads Sanders among pledged delegates by 1,243 to 975, according to the Associated Press. When party-selected super delegates are included, Clinton had an estimated lead of 1,712 to 1,004, according to the AP, with 2,383 delegates needed to clinch the nomination.

Sanders, noting that "we won six out of seven contests in the last 11 days," told ABC he can still get strong superdelegate support if he keeps winning. "You’re assuming that every superdelegate who now supports Secretary Clinton will stay with her," Sanders told ABC. "You’re not taking into consideration the fact there are hundreds of delegates, superdelegates, who have not yet made a decision.  We think we can win many of them."

Sanders told CNN's State of the Union: "A lot of these superdelegates may rethink their position with Hillary Clinton."
