This recommendation of the FEC staff would allow Price to do that. A 501(c)(4) can now do lots of election and political activity without getting in trouble with the IRS.

UPDATE: It may be that the limits this 501(c)(4) is putting on itself, at least until it spends down Price’s campaign funds, may curtail some of the political activity it would engage in. But the benefit of this structure would be to shield future donors from public disclosure.
