Louisiana’s alleged governor PBJ is the poster boy for “Dark Money”

Republican advantages may go beyond sheer numbers. In “America Next,” Gov.Bobby Jindal (R-La.) has the backing of the first single-candidate “dark money” group to report spending to FEC this cycle. This 501(c)(4) social welfare organization, which can accept unlimited donations without revealing donors’ names, is one of several functioning almost as de facto arms of the campaigns themselves, continuing a trend that began only in 2014.
While Democrats, including Hillary Clinton, have single-candidate super PACsproviding them big-money firepower this cycle from sources that are disclosed to the public, they have not yet taken the step of incorporating single-candidate dark money organizations into the mix. That’s not to say that liberal dark money groups are entirely silent: Planned Parenthood has reported spending $74,057 attacking Clinton’s opponents.
America Next has already helped Jindal in a least a couple of ways: The group bought $340,537 in television ads explicitly supporting Jindal’s candidacy for president after months of paying Jindal’s travel bills as he jetted around the country giving policy speeches before declaring himself a candidate.
