First of all, it IS the only factor as far as the NRA is concerned.
...I see a real problem with the way the NRA indirectly (almost directly) suggests who to vote for (typically Repubs); as important as the gun issue is it is not the only factor in choosing a candidate...
They are a SINGLE ISSUE association and therefore their recommendations are based exclusively
on that SINGLE ISSUE.
If other factors are important to you then you need to get that information elsewhere. You can not get it from the NRA because they only collect and disseminate information based on one factor.
Second, while we all understand that there are many factors that should be considered when choosing a candidate, at TFL we're only going to discuss one of those factors in any great detail because TFL is focused on firearms.
