I'm sort of jealous. They had a referendum on Scottish independence and they honored the outcome. I'd love to have an up/down national vote on abortion, gay marriage, gun background checks.. At best here in the US, you're voting for a derivative, you're electing someone on the wish/hope that they support your issues if they get a chance or opportunity to of if they're willing to use political capital to actually propose the issues.. With something like abortion, it's at least 2 derivatives removed, you're voting for someone who will hopefully select a court justice (should they get to) that will align with your issues should the opportunity ever arise for them to make a judgement on it. And what's more perverse, there are a lot of single issue voters that take that multiple derivative issue situation as the only issue that matters.
It'd be an interesting experiment if nothing else.
