Next stop, removal of the tax exemption of ministries that preach politics from the pulpit.

Yeah, but a tie in SCOTUS neither overturns nor upholds the lower Courts ruling.

It merely lets that ruling stand.

With the distinction that the ruling does not apply nationally, and may be (likely to be?) challenged in the future.

So, this topic does not yet seem to be resolved nationally.

That's how I understand it.
