> As a side note, 508(c)(1)(a) can also speak about politics while 501(c)(3) are forbidden from doing so. Er, that's not exactly true. 501(c)(3) aren't forbidden from speaking about politics. There are restrictions on the ways in which they can (e.g. no overt party affiliation) and the degree to which they can do so. For example, they can spend time lobbying, but only 10% of their time and only 10% of their budget (I don't remember if it's still 10%, but that used to be the number). Oftentimes, 501(c)(3)s will have a separate, associated entity that they use for their political lobbying, to avoid having to keep track of their resources when mixed and prove that it's under this threshold.
