In news from the campaign trail, Democratic candidates Hillary Clinton and Bernie Sanders have raised more money than any other candidates over the last three months. Clinton raised $30 million. Sanders raised $26 million, despite continuing to refuse to accept campaign donations from corporations and super PACs. Ben Carson raised $20 million, the most of any other Republican candidate. At this point, the 2016 campaign is significantly outpacing recent election cycles in campaign contributions. Half the money raised so far has come from outside groups like super PACs.
