[EL] Criticism of candidate by 501(c)((3) during campaign -- permitted?

[jon.roland at constitution.org]

What I stated is what is the most that can be reasonably wrung out of
vague statutes and regulations. The rest is the typical invention of
agents who write instruction booklets and pretend they are legislation,
but which deserve to be held void for vagueness or a violation of the
nondelegation doctrine.

Practice is practice, not law.
