Could Warren's Ban On Big Money Help Trump?
Elizabeth Warren has sworn not to do large private fundraisers if she becomes the Democratic nominee.

President Donald Trump and the Republican National Committee already have a large head start on raising money.
Business Insider believes Democratic candidates should be principled but pragmatic when it comes to fundraising choices.
