I have to agree with Open Minded on this one. I've not seen any comment on any station that reflected this guys political beliefs. In fact, the sheriff said they don't have any idea of motive yet as did his family.
There will be time for this type of conjecture after the facts are known. Until then, we should simply feel for those most hurt by this lunatic.
No politics on this one. He attacked Americans, not republicans or democrats.
