Super PACs and other groups dominated the race for the Republican presidential nomination last month, raising and spending tens of millions of dollars outside the traditional campaign system and playing a key role in extending an already tumultuous contest, according to new disclosures filed Monday.
One such political action committee backing Mitt Romney raised more than the candidate’s campaign in January, when it spent nearly $14 million on his behalf in the states that held early primaries and caucuses. The group, called Restore Our Future, leans heavily on six- and seven-figure donations from hedge fund managers and other investors.
