Hardly any is back-channel. Asking the Nuncio to have Reagan declare the unborn as Vatican residents was, as was my expereince at NARAL, but most of it is based on published reports, like the getting rich on pro-life donors by Vigure and their attempt to use the personhood movement at the state-level to bring back its base, which was fading at no action. Trying to get both Clinton and Obama to call the movement a fraud was real. Obama did and got the Catholic vote. Clinton forgot and lost it by a huge shift. The PBAA as a stalking horse is appraent from the RTL Amicus briefs, and Jay Sulkolov never got back to me on using the 14th Amendment to justify the Act, which he did not want to do, so instead Kennedy used the Commerce Clause. The associate I worked with on the other side rejected the same approach to overturn the act because it did not cite the proper authority, but they figured correctly that the Court would simply use that authority anyway to keep the Act.
