There's a lot of online support you can give to a campaign from outside Canada. Even things like media monitoring or monitoring online activity.... That's going to be very difficult to control, because it can be done from a beach in Australia, or anywhere. I mention the beach in Australia because that's where the website for Leadnow was created, apparently. That's part of it.
I'll give you another example. The online donation mechanism for Leadnow was created by an organization based in Washington, D.C.
Whenever things online can be prepared by an online consultant anywhere, it's hard to track the expenditures.
