I also am praying for Rep. Gilford's recovery. It makes no difference which letter follows her name (D or R), she is a victim. As for the alleged shooter, if it is who has been reported, he would appear to be mentally ill, based on his ramblings on You Tube, I would say he is neither left wing or right wing. Schizophrenia doesn't have political leanings. Everyone is a threat to a paranoid personality.
