Wall Street Journal: “The craft of opposition research–finding information that might put an opponent in a negative light–has long been a staple of political campaigns. This year, independent groups are taking a leading role, adding to the research done by candidates and party committees.”
“Like other parts of electioneering, such as buying TV airtime and soliciting donations by phone, opposition research is becoming a specialty of third-party groups. Two of the most prominent are America Rising, a 67-employee group that takes aim at Democrats, and American Bridge, whose 80-plus-staff targets Republicans. Both are backed by prominent donors–investor and money-manager George Soros, for example, has backed Democratic-aligned American Bridge, while hedge-fund founder Ken Griffin has given to America Rising.”
