Sorry Lion, I don't know how we can disassociate the FDA from politics. But I will try going forward.
We can disassociate the FDA issue from partisan politics pretty easily. You don't have to be a Republican to acknowledge that the FDA is fallible and corruptible, and you don't have to be a Democrat to acknowledge that large corporations can be unscrupulous. From there, it's just a matter of realizing that money and power attract one another. As the saying goes, it takes two to tango.
Anyone who would tout the moral authority of the government on the basis that CEOs are worse misses the point: CEOs offer generous salaries to outgoing government officials; therefore they influence government agencies' decisions. It happens almost daily. Which is worse -- the official who abused the public's trust by taking a bribe, or the businessman who proffered the bribe? That's a trick question: the answer is, "Who cares?"
In this case, the FDA's record of anti-rational and malignant behavior (with respect to vaping) is clear, and therefore our cause for concern is clear. There's still a chance that the FDA will do the right thing, but we've no good reason to believe that they will.
