You should. NRA has developed a very bad reputation among the RKBA crowd about it's inside politics backdoor closed room dealings.
It is the primary reason local and national splinter groups made up of the OTHER 76 million US gunowners have sprung up everywhere from JPFO to GOA to SAF et.al.
I would always trust the locals rating over the NRA. In this particular instance the local GRNC scrutinizes the ENTIRE voting record of candidates rather than just one or two high profile votes.
National Magazine Gunwriter David Codrea explains his problems with the NRA well:
