He is taking on people that 20 year top Democrats and top media people would be careful with. If he thinks the NRA is a nice soft puffy little group, he is in for a rude awakening.
The NRA has A LOT of BIG influence. There are tons of important people in D.C. who tip-toe around them. And this little acne-faced pipsqueak high school punk thinks he will take them down? LOL, not a chance. And as has been said over and over he was NOT there and he is NOT a survivor. In the military we call this STOLEN VALOR.
He had a perfect opportunity to leverage his fleeting fame for his future benefit. But he blew it IMO. And the strike on McCain was the nail in the coffin. The best thing he could have done is to be 'opposition', but to do it in a respectful intelligent way.
He could have met some important influential people who can help him later. Instead he came across as angry, mean-spirited, and belligerent. But, what would you expect from a kid?
