Russ Choma for Mother Jones:

Jeb Bush officially declared that he was seeking the presidency two weeks ago, yet political observers have assumed he made the decision long ago and may have remained a shadow candidate for strategic purposes. Official candidates are not permitted under campaign finance law to coordinate with super-PACs, which can raise unlimited amounts of money. As a supposedly undecided candidate Bush could work closely with Right to Rise, the multimillion-dollar super-PAC supporting his candidacy. But recent statements by one of Bush’s top political allies suggest Bush may have coordinated with Right to Rise even after he technically qualified as an official candidate.
