Vaping is a big deal to us. The candidates briefing papers probably have a list of 200 major issues, and 5000 minor issues, with vaping near the bottom of the second list. And not because "V" is at the wrong end of the alphabet.
I'd love to see that sort of list, rather than the speculation of it. I think being fair, that vaping is in top 100 and right now is likely near the bottom 20 of that list.
Why would any branch of government want to help us?
Because one party could invoke agenda/policies that vapers scream about and many of those vapers are voters. So, like any issue (ever), the elected representatives would hear from the citizens that government has gone too far and needs to be reined in.
Judiciary branch has already helped us, in a significant way.
FSPTCA, while supported in a rather bipartisan way (though far from unanimously) could easily have exemptions put forth, and thus it would be pretty visible for congress or POTUS to have positions that state exemptions are reasonable or not. Again, all this having to do with overreach.
Standing up for vaping would cause a huge loss of revenue at every level, affecting both parties equally.
How so? Or how is this different than any of the major issues?
And outrage among some of their most powerful donors. And giving the other party a big stick to beat them with. They might get the gratitude of the small percentage of vapers who are even aware of the political shenanigans, but they know that in the current, carefully nurtured climate of mutual hatred nobody is going to change their vote because of a single issue. Did I mention doing the right thing? No, for some reason I didn't mention that.
From thread I started on ranking of issues, I'm fairly convinced that some vapers will be single issue voters. Vast majority will not. But the closer we get to November 2016, the more I think vaping has a chance of popping up on national radar and/or that politically aware vapers will have clear indication on which candidates are likely to make things worse or possibly make things better. I currently don't see a candidate who would make things better, but do see at least 2 candidates who could make things worse.
If it had become a partisan issue then maybe. If one party was exclusively forcing the battle against vaping then the other party might be willing to take the hits and support vaping. But that isn't going to happen because they both feed out of the same trough. I know some folks think it really is a partisan issue, but that's not my problem.
Because FSPTCA happened under one party's watch and because partisan politics are currently alive and well, then it stands a reasonable chance that vaping will be framed as a partisan issue. Especially if one considers that in 2014-15, congress did have hearings on the issue and those hearings were very partisan, and the side that wasn't visibly against vaping/us, was saying things that a politically aware vaper could support.
In essence, your post comes down to whether or not vaping will make its way onto the national radar before 2016 elections. I think it will and I think it won't be considered a top 10 issue for any candidate, with possible exception that those against us might see it as way tie BV to BT and justify overreach in that way. But we don't need it to be top 10 for it to be dealt with in significant way. Just a message of 'government will stop the overreach on this issue' would go a long ways.
Candidates and current government officials who are about less government / overreach will be people that could easily be seen as helping vaping industry / community. Whether or not they do is anyone's guess. Just like every other issue that these same political types weigh in on.
And again all this relates to OP because clearly the people that commissioned study to suggest vaping doesn't help with quitting smoking are people that overwhelmingly support one party in America. This has already been shown in this thread.
