Sadly, Trump is very sane and knows exactly what he's doing. This isn't a case of a lunatic who's frothing at the mouth and baying at the moon, all of his ranting and raving about Orlando is callously calculated and designed to appeal to his frightened and angry base of supporters who've fully bought into his neverending rhetoric that the monsters are banging down our door, and only Trump can save the country from Islamic Armageddon. In other words, it's con, one of many by Ol' Orange Ass, but clearly his most dangerous.
And that's just what the NRA and the gun industry wants, to keep the country's focus on those brown skinned, bloodthirsty madmen in the hope no one will pay attention to the fact that lax laws authored by the NRA's puppets in the Republican Party allowed psychopaths, HOMEGROWN, Caucasian psychopaths free and easy access to weapons like what Omar Mateen used so they can wantonly maim, cripple and kill by the boatload.
