Parkland, FL massacre will guarantee Republican loss 2018. (Purely an opinion of mine) Parkland is a conservative stronghold now fiercely motivated against guns (unlike Vegas where the crowd was from different parts, cannot be from a strong organization, and some in the Country Western crowd accepts the risks, from statements made). There is a strong desire even by conservatives for better gun control laws, and that is only growing. If the Republicans do not act to make controls, you will see a migration of support going to the Democrats. If Republicans do make gun control laws, you will see a similar loss of support by gun advocates. I predict to keep Republican support, there will be gun laws enacted since gun supports will never vote Democratic. Either way, it will be Republican blood bath, and Trump will likely loose 6% of his already small core base. Side note about local gun politics in FL.
