I think that's correct. I've found several sources who refer to the application, but none that say the annulment was granted. Kerry divorced her, and then remarried without an annulment. I can't see how he can claim to be an observant Catholic after that.
It's also noted that his first wife, Julia Thome, came from a family that's worth close to $300m. He does like 'em rich, doesn't he?
