> Introducing sane gun regulations have polled above 66% but the representatives we have in washington won't touch that with a ten foot pole.
And do you know why it is so? The popular adage is "gun lobby throws money at representatives", but it's actually not true.
The reason why gun control doesn't get traction despite popular support is because those polls that measure support or opposition don't measure the dedication of people expressing it. The majority, when asked about gun control, support it, yes - but most don't feel particularly strong about it, and extremely few consider it a make-or-break single issue. So when it comes to voting, politicians know that they can get those people's votes even if they don't go for gun control, riding on other issues.
OTOH, NRA (and other gun rights orgs) have a very effective resource, and that isn't money - it's membership. Specifically, it's the subset of its members that is laser focused on gun legislation, and the majority of whom consider it their single most important issue. Because of that, they're likely to turn out in the primaries, and vote based solely on that one thing, ignoring everything else. Furthermore, NRA (or rather NRA-PVF specifically) facilitates it by compiling dossiers on various candidates in all races across the country, and publishing them together with voting guides. So what this all means is that any Republican who openly supports gun control will find it hard to get through the primary. And, conversely, not supporting it is not a big downside in the general (D voters will vote against you anyway, and R voters will vote for you anyway).
This is changing lately with the rise of left-wing, ideologically motivated groups that target primaries in a similar way, like Indivisibles, which means that Dems these days are a bit more likely to pick it up. But it's still a litmus test for Republicans, and for as long as that remains the case, you're not going to see 70% popular support translate to 70% legislature votes.
By the way, we had a very good demonstration of this recently. Remember the whole bump stock kerfuffle? When ATF announced that it's reviewing its categorization of them, there was a public comment period. Here's how it went:
"Of the more than 17,000 public comments received so far by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), a review by Reuters of 4,200 turned up only 10 favoring the bump stock ban. Almost all the rest criticized the proposal as heavy-handed, unnecessary or unconstitutional."
Funnier still, most comments expressing support for the ban were form letters, while most comments expressing opposition were not. This despite the fact that over 80% of the population support the ban, according to the polls - just not enough to bother leaving a public comment on the Internet expressing that opinion, much less prioritize it in their voting choices.
