"What did he do when he became Washington Joe? He voted as a member of the team," Raese said.
"I'm a proud West Virginia Democrat - I am not a Washington Democrat," he said.
He said his political beliefs were shaped by his upbringing, which emphasized hard work and being held accountable.
"I've never been called a liberal," Manchin said. "I'm a fiscal conservative and a social moderate."
While he believes programs like Social Security, Medicare and Medicaid are vital safety nets to protect seniors and the poor, Manchin said they've been expanded beyond their original intentions.
Manchin said programs to help the poor were "not intended to be generational welfare."
He said the federal government needed a strong financial backbone so it could help the poor, but he said that did not mean he believed in redistributing wealth.
"I'm not going to take from you and give to them," he said.
But Raese said Manchin's words don't match his actions. He said Manchin has had opportunities to change unpopular Obama administration policies and has failed to act.
"Joe's been there for two and a half years. Has anything changed? No," Raese said.
"He has to be a Democrat, he has to play the game and play with the guys on his team," he said. "Once you are a Democrat in Washington, you are a Democrat plain and simple."
Manchin maintained he is independent and said he has been rated one of the most centrist and moderate members of Congress.
"The only team I support is West Virginia's and America's team," Manchin said.
The West Virginia Coal Association has endorsed Manchin over Raese in this year's Senate race.
Raese said the coal association was "shallow" and acted like "lemmings" in supporting Manchin.
Manchin said he has built a track record of working together with people of both parties to get things done. He said that's the kind of person voters need to send to Washington, not someone with a rigid ideology who would oppose working together for change.
Raese emphasized the need for Republicans to win five more seats and gain control of the Senate so Reid, Boxer and other Democratic leaders of the body can be replaced.
