Hmm. I wonder how the US survived before 1954?
There simply is no rational justification for denying churches the right to endorse candidates and participate in the political process.
In real life, churches will be very cautious about this, so as not to drive away members of opposing political persuasions.
While it is virtually certain that fake churches will be set up to launder dark money, campaigns are free to point out the fraudulent nature of such “churches.”
