WASHINGTON – Sen. Bernie Sanders said Sunday he’s the one presidential candidate who can stand up for working class people, take on big-money interests and fight for civil rights.

“I am that candidate,” Sanders declared on MSNBC’s Politics Nation with Al Sharpton.

In previewing how he’ll take on Hillary Clinton in Tuesday’s first Democratic debate, Sanders said he can tackle income inequality in America because he isn’t backed by Wall Street interests.

“I do not have a super PAC,” Sanders said. “I don’t represent the billionaire class. I don’t represent corporate America. I don’t want their money. We raise money differently.”

“I know what I stand for,” Sanders added. “Hillary Clinton knows what she stands for. Let’s have that debate.”

The Vermont senator who once was run off a stage by Black Lives Matter protesters said he’s a fighter for civil rights.

Sharpton said he was impressed with Sanders’ record of marching with Dr. Martin Luther King Jr., leading sit-ins and protesting segregated housing in Chicago.

“You have probably the strongest civil rights record in terms of activism that I’ve seen in this last season of candidates,” Sharpton gushed.

“It is a fact,” Sanders responded, pointing out his was even arrested for his fight for civil rights and low-income people. “I am the candidate to make that fight most successfully.”

Sanders has been leading Clinton in polls in New Hampshire, while the former New York senator is first in Iowa and nationally. He’s drawn enthusiastic crowds with rallies topping 20,000 people. And he raised nearly as much money as Clinton this quarter even though he attends few traditional fundraisers. He raked in $26 million in three months largely through small-dollar web contributions compared to Clinton’s $28 million.

In a separate interview on NBC’s “Meet the Press,” Sanders outlined more differences with Clinton: He wants Medicare for all and free college. He believes there hasn’t been a single US trade agreement that’s been fair to the American worker, including the latest Trans-Pacific Partnership agreement: “I do not want American workers to compete against people in Vietnam who make 56 cents an hour for minimum wage,” Sanders said.

Clinton recently came out against the TPP deal as well.

Sanders said he differs from President Obama because he’ll continue to engage the American people in a political revolution as president.

A Republican House Speaker, for instance, will be forced to work with him because of public pressure.

“He’ll have to look out the window and see a million young people demonstrating and marching in Washington saying, ‘You know what? We want to see affordability in college.’”

The Democratic CNN debate airs 8:30 p.m. Tuesday in Las Vegas. Sanders and Clinton will be joined by Martin O’Malley, Lincoln Chafee and Jim Webb.
