WATCH: Bernie Sanders rips 'horrific Trump effort' and birthers in MSNBC town hall

With fans and supporters chanting “Bernie! Bernie! Bernie!”, Vermont senator Bernie Sanders declined to answer the question of whether the person with the most delegates and votes should be the Democratic presidential nominee.

“If we are behind in the pledge delegates, I think it’s very hard for us to win but we are going to make the case also... that we are the stronger campaign in taking on Donald Trump or any other Republican candidate,” Sanders said. “And I think that most other Democrats out there wanna make sure that some right-wing Republican doesn’t become president of the United States.”

Sanders characterized a large component of the Republican voter base as “obstructionist” and beholden to “far-right” candidates like Donald Trump, which would preclude cooperation with Republicans in Congress.

“I think the Republican Party, as I mentioned, has moved very very far to the right,” Sanders said. “People who are active in the horrific Trump effort, the birther movement, people who are very hostile to immigrants. You see Trump talking about and referring to Mexicans as immigrants and rapists.”

When pressed, Sanders says that he will help elect whomever it takes to keep Donald Trump or another Republican candidate from being elected president.

“I will do everything in my power to make sure that no Republican gets into the White House in this election,” Sanders said.
