evidence: Sanders had raised roughly $71 million more than Biden through early March, taking account of both money raised by the candidates’ campaigns and by outside groups supporting the candidate. Combined, Sanders and his allied groups have raised more than $180 million, compared with $109 million for Biden and his allied groups. Sanders does have an edge in "small-dollar" donations — those below $200. About 55% of Sanders’ money was raised that way, compared with 36% for Biden.
