Just to get a sense as to what sorts of things there are, you mentioned that it's difficult for you to determine where someone is crossing the line and promoting a specific candidate or a specific party unless you can see some demonstrable, obvious connection where there's been an agreement made.
I'll throw out an example. Potentially, what if a union were to have paid employees for door-knocking or canvassing for a specific candidate? Would that be required to be reported by that candidate's campaign or that party's campaign? Or would that still be able to be third party spending?
