Sanders has also gained more support with African-American voters according to a poll conducted by VICE News and Ipsos.
While 54 percent of African-American voters said they would consider voting for Biden, 56 percent said they would consider voting for Sanders, numbers the poll considers to be a "statistical tie."
Sanders also has a 10 percent lead over Biden among the Hispanic community with Sanders grabbing 47 percent of its support, while Biden has 37 percent.
"Despite frequently being described as a 'socialist' or 'too liberal,' Bernie Sanders has as many, if not more, minority Americans considering voting for him as any other candidates," Ipsos Public Affairs Vice President Chris Jackson told VICE News.
