Political Action Committee funds, are not campaign funds. So they don’t mind the same rules.

And one of the ways to launder campaign cash after an election is transfer to a PAC that they control…

A significant amount of that article is about it. That’s why I thought it was relevant enough to link

There is one significant loophole in this process, however. That is the little-regulated leadership PAC, a political committee that is directly or indirectly established, financed, maintained or controlled by a candidate or an individual holding a federal office. A candidate can opt to transfer their money into one of these entities.

“And the rules for leadership PACs are completely different than the rules for your official campaign committee,” Deborah explains, “So the personal use rule doesn’t apply there. You can use it for travel, you can use it for dinner, concert tickets, all in the name of fundraising. There’s just not that much scrutiny on it. And politicians have used their leadership PACs quite lavishly. So that’s that’s another that’s a huge loophole that I mean, neither side seems keen on closing at this point.”

It’s important to note that the FEC has a number of vacancies right now. In order to meet and review audits and complaints, the Committee must comprise at least four members. Currently there are just three, and Congress is unlikely to confirm a fourth soon. Even if someone were to notice wrongdoing or violation in the bounds of a leadership PAC, there isn’t much that could be done.

Do you think that’s more than the “victory fund” has taken from state parties this cycle?

If I took $5 and gave you $2 back how would you feel about me bragging about giving you $2 out of the kindness of my heart?
