The problem for the PAC is that it can’t coordinate legally with Bush on where to spend that fortune. It has to do its own thing, making educated guesses about where and how to advertise or otherwise contact voters.
Unless, that is, there’s public information it can act on. Bush’s campaign can’t call Right to Rise and say, “Hey, we need help in Iowa.” It can however, make an internal document public for the world — and the PAC — to see. Carpenter’s point? That was precisely the plan.
