Attention, parents of political candidates. There is now a way to spend an unlimited amount on your child’s campaign for Congress, completely ignoring that annoying $2,600 legal limit on what you can give. All you do is set up a “super PAC” for your kid and start writing checks. It’s not much harder than that 529 account you used for the same kid’s college education.

That’s what Martine Rothblatt, the founder of Sirius Satellite Radio, did for her son, Gabriel Rothblatt, who is running as a Democrat for a Florida congressional seat against a three-term incumbent. A group calling itself Space PAC has spent $58,000, so far, in promoting Mr. Rothblatt’s campaign. It has raised $225,000, all of it from Martine Rothblatt.

Mr. Rothblatt, trying to maintain the veneer of independence required by the law, told USA Today that he had no idea that the super PAC was working on his behalf until he saw some of its yard signs with his name. The issue simply has not come up in family conversations, he said. “You don’t want to, in a casual conversation, cross a line that can turn around and bite you,” he said.

Sorry, but that’s preposterous. Space PAC is no more independent from his campaign than the candidate himself. But this fictional independence is going on all over the country.
