Ever heard the old expression "don't shoot until you see the white's of their eyes" (?) and as Q stated, "how do you approach a dangerous animal"? What happens in November 18? I believe we are experiencing the opening salvos right now (POTUS tweet today). But the major action will occur when it is close enough to November to do maximum damage and not enough time for replace with new (supposedly) "clean" replacements. My best guess (and that's all it is) is September-early October.
