1. When they raided Maralago and found documents that should've been with NARA (and then even more that the FBI missed apparently), it proved trump had lied about not having any more documents.
2. Trump has openly talked about going after his political rivals.
3. It's not simply homes being raided that is the issue. It is whether or not it was justified. If they find proof she did something illegal, fine. Cool. Lock her up or whatever punishment is warranted. But if nothing happens from this... Well.. I guess add it to the pile of trump's failed lawfare with Hillary Clinton, Barack Obama, James Comey, Letitia James, Fauci, etc. Then just say there was a cover up or whatever.
