I DON'T SEE HOW THE BAGGERS CAN MEET THIS STANDARD

Ezra Klein highlights an IRS requirement for 501(c)4s, also known as social welfare organizations:

A 2003 IRS document says that “organizations that promote social welfare should primarily promote the common good and general welfare of the people of the community as a whole.” It goes on to give pages and pages of examples. “A corporation organized for the purpose of rehabilitating and placing unemployed persons over a stated age,” for instance. Or “a corporation formed to provide a school district with a stadium.” “A memorial association organized to study and develop methods of achieving simplicity and dignity in funeral and memorial services,” qualifies, as does “an organization that conducts an annual festival centered around regional customs and traditions.” Nowhere does the IRS mention “an organization formed by top political operatives for the clear and obvious purpose of reelecting or defeating the president.”

There's no way that spreading Bagger agit-prop can be considered social welfare.
