Hillary Clinton's ties to financial institutions like Goldman Sachs would limit her effectiveness as president, Larry Sanders, the older brother of Democratic presidential candidate Bernie Sanders, said in an interview aired Monday evening on CNN. And unlike Clinton, he suggested, the senator from Vermont holds the same policies and principles he has held for much of his adult life.

"Hillary Clinton — Bernard has been very careful to say he respects her, she's very bright," said Sanders, who is the health spokesman of the Green Party of England and Wales, in an interview with CNN's "Amanpour."

Emphasizing that he was speaking for himself and not for "Bernard," as he calls his brother by his full name, Larry Sanders remarked that Clinton's "background of being in the same team with people like Goldman Sachs and all the rest of those people, whose greed has brought us to a very sorry path, I think that limits her effectiveness."

Bernie Sanders has also criticized Clinton for her paid speeches to Goldman Sachs in recent weeks, demanding that she release the transcripts of those speeches.

Asked what his younger brother needs to do going forward, from next Tuesday's New York primary and beyond, the elder Sanders said that his brother just had to be true to his roots.

"Well, Bernard has the advantage that he doesn't have to keep shifting his policies. By and large, he's had the same policies for 30 or 40 years. So he knows where he comes from and he knows what he wants to accomplish. He's got incredible stamina," Larry Sanders said, adding, "I think he's come this far, he'll go all the way."

At another point in the interview, Larry Sanders called the Republican primary discourse "quite ridiculous" while praising the Democratic side of the race in much the same way Democrats are wont to do on this side of the Atlantic.

"The Democratic side has been much more about issues. Ms. Clinton represents a very important strand of American politics. I think Bernard is right to call it establishment," he continued. "She gets her money and her support from people who have been doing that for her and for others for many decades. Bernard comes from a different background. I think they're very legitimate opponents."
