The Ultimate Political Litmus Test

I believe I've struck upon the perfect behavioral litmus test for political affiliation. I haven't tested it, but it feels inarguably true:

Liberals choose Sugar In The Raw, while conservatives choose Domino (sugar substitutes are bipartisan).

As a centrist, I see the folly of both sides. Choosing Domino reveals a lack of imagination and a mulish inclination toward complacent conformity. But Sugar In The Raw is gestural fakery, exploiting the vain appeal of shallow faux-high-mindedness.
