Elections

Organizations described in section 501©(3) are prohibited from conducting political campaign activities to intervene in elections to public office.[29] The Internal Revenue Service website elaborates upon this prohibition as follows:

Under the Internal Revenue Code, all section 501©(3) organizations are absolutely prohibited from directly or indirectly participating in, or intervening in, any political campaign on behalf of (or in opposition to) any candidate for elective public office. Contributions to political campaign funds or public statements of position (verbal or written) made on behalf of the organization in favor of or in opposition to any candidate for public office clearly violate the prohibition against political campaign activity. Violating this prohibition may result in denial or revocation of tax-exempt status and the imposition of certain excise taxes....

I doubt there is a church of any size which is not in violation of 501 © (3).

And to put an even finer point on it, there is an organization here in the U.S. which is organizing and urging churches to wantonly violate these restrictions on them.

I'd say that a large measure of churches attempt to remain in compliance (and stick to urging people to vote, to register, to become informed voters, so-called "issues advocacy") and avoid that which is not allowed (advocating for or against a candidate up for election).

But as noted, there is a substantial number that feel it is their right to be politically active.
