Lots of misunderstanding and confusion in this thread. Not to pick on anybody, but the below post is an example.
No tax exempt organization is allowed to interfere with politics, its not just churches.
Please be aware that political activity is TAX EXEMPT.
When a candidate's campaign receives a contribution, it is NON TAXABLE.
Political PACs, Super PACs and the like are TAX EXEMPT (under section 527).
The below post gives a hint as to the correct answer:
Congress passed the laws over 50 years ago. 10 second Google search:

From the link, prime example:
A definitive court case on the issue of free speech and political expression is Branch Ministries Inc. versus Rossotti. In that case, the court upheld the constitutionality of the ban on political activity. The court rejected the plaintiff church's allegations that it was being selectively prosecuted because of its conservative views and that its First Amendment right to free speech was being infringed.
The court wrote: "The government has a compelling interest in
maintaining the integrity of the tax system and in not subsidizing partisan political activity, and Section 501(c)(3) is the least restrictive means of accomplishing that purpose."
The poster even bolded the most relevant part.
What would happen to churches that campaign for a specific candidate is that donations to them would not be deductible by the donor. The church, like any PAC or campaign, would still be tax exempt.
The point here is to NOT allow churches to become a PAC or campaign where the donor gets a deduction for his/her contribution. If we allowed that we'd have to allow contributions to PACs and campaigns. And so far Congress has decided that such political contributions shall not be deductible.
(There is nothing in the Constitution, or common sense, that says non-business expenditures, such as political contributions, must be allowed as a deduction for computing income tax. For whatever public policy, or other reasons, Congress has decided that some non-business expenditures may be deducted for income tax. E.g., real estate taxes, mortgage interest and medical expenses.)
