Let's ask the Sanders question of DU in a more general way.

Should PACS be allowed to, not simply promote issues, but fundraise for campaigns? Is it not the definition of money-laundering that, for instance, Ted Cruz super pac "Keep the Promise" raises millions from select high-dollar donors and use that money to shake down small donations from individual donors to finance his official campaign?

So when Ted goes to the home of a prominent fundraiser such as Bob Murray of Murray energy, should the resulting donations (the per-plate price of the dinner is twice what is allowed to the official campaign) to Cruz's super PAC be diverted into fundraising for the Cruz campaign? Does this not violate the spirit of the cap on individual donations?

This is essentially the question Sanders is asking.

I think the answer to this question should be no, but I've noticed that the definition of "progressive" has become fairly malleable of late.
