National: Some Candidates, Super PACs Draw Closer | Wall Street Journal
Republican presidential candidates are largely abandoning the caution of past campaigns in relations with the super PACs backing them, testing legal limits as the independent groups take over more functions from campaigns themselves. Super PACs, independent political organizations that stood on the fringes of the 2012 presidential election, are now moving to the center of the current campaign, changing the way presidential races are financed and run. Four years ago, the boundaries between the groups and the campaigns were clear. Now, as more money flows into super PACs instead of campaign accounts, the lines are blurring, making it hard to distinguish between the two political machines.
