The second round of DemDebate between US Democratic Presidential candidate Hillary Clinton and Bernie Sanders, before the next phase of elections in Iowa, took place at the University of Wisconsin-Milwaukee on Thursday for PBS “News Hour.” The duo debated on a range of issues, including health, immigration and racial inequality, which led to a degree of heated exchanges between the two.

Sanders accused Clinton of being too indebted to the interests of the Wall Street, which she once represented as a US Senator from NYC.

“Let’s not insult the intelligence of the American people,” the Reuters quoted him as saying. “Why in God’s name does Wall Street make huge campaign contributions? I guess just for the fun of it, they want to throw money around.”

Clinton defended by saying donations do not necessarily mean she was indebted to the Wall Street and noted that President Barack Obama also accepted donations from Wall Street during his campaigns.

“When it mattered, he stood up and took on Wall Street,” she said.

Clinton, who faced a double-digit-loss in the New Hampshire primary, argued that Sanders should set realistic goals and be honest with the voters about the difficulty of implementing his trillion dollar policy plans.

Clinton tried to assert during the DemDebate that, the voters would be interested to know Sanders’ financing plans of Medicare for all and free public colleges and that these details would be more important than his inspiring political message.

Clinton railed against Sanders saying he has not been transparent enough regarding the cost of his programs, which include the proposed expansion of government’s health care program.

This is not about math — this is about people’s lives, and we should level with the American people,” the New York Times quoted Clinton as saying. “Every progressive economist who has analyzed that say the numbers don’t add up.”

She added, “We should level with the American people about what we can do to get quality affordable health care.”

To this Sanders said, “I don’t know what economists Secretary Clinton is talking to. That is absolutely inaccurate.”

Both Clinton and Sanders demanded reforms in the criminal justice system and vowed to address the difficulties faced by the Afro-American communities. Sanders even went to the extent of saying that the racial situation would “absolutely” improve under his administration, the CNN reported.

Though the debate was characterized by sharp differences between the candidates, it was devoid of the kind of verbal attacks that marked the New Hampshire debate last week between the two.
