Bernie Sanders is outraising Hillary Clinton — and he needs to, because he’s spending more.

The senator from Vermont outraised his Democratic primary opponent in February, the Washington Post writes. He pulled in $43.5 million to the former secretary of state’s $30.1 million. But campaign-finance details show he plowed through far more cash, spending nearly $41 million to her $34.3 million. That left Sanders with $17.2 million in the bank as March began, while Clinton had $30.8 million.
