It's definitely the putrefied rotting souls that the flies are attracted to.
It brings to mind the book, "Lord of the flies." The contrast will only be by the scale of insanity and destruction. If the demonicrats win in November,the devastation of our world will be total. Along with that, the wickedness and evil perpetuated upon them by Satan will make them wish for death.
My favorite line from that book when I was a kid remains in my head to this day and helped mold me into the superior human that I am today.
The Lord of the Flies = Satan
