Almost $1.5 million has been spent against Donald Trump in the past seven days, more than six times as much as every other candidate combined.

More than $1 million of that recent spending comes from Our Principles PAC, an independent super PAC whose sole mission is to bring down Trump. Priorities USA Action, affiliated with Hillary Clinton, spent $25,000 against Trump. Trusted Leadership PAC, affiliated with Ted Cruz, also spent $25,000. Club for Growth Action, an independent super PAC, spent a lesser amount against Trump.
