Don't be disgusted with them - reasons have already been well covered above. IMO it's a very good thing that the NRA is getting away from the "Republican Stooges" image of the past - this will win them more friends than enemies.Why did I purchase a life membership in the NRA? They just announced that they are endorsing Scott Murphy, a left-wing liberal over Chris Gibson a conservative, pro-second amendment, decorated veteran. Gibson recieved at top rating from the NRA and they snub him. This is a congressional race in upstate NY.
How do I get my money back? Never another dime to the NRA unless they change this endorsement.
In my area, the NRA endorsed candidate is also the other side of the fence from my political views (I do vote the party, not the person) - I'm not a single issue voter, therefore, I won't be able to vote that way. However - if an endorsed candidate was in tune with my political views, the fact that he/she was Pro 2a, would probably swing me to vote that way over another candidate from the same party - and it would be thanks to the NRA for letting me know.
Unless you are a single issue voter (which 99% of the population aren't), the fact that the NRA endorses a candidate should just be taken into consideration at the polls, rather than be taken as the be all and end all.
