I used to hate the word consumer too (I don't love it now either) but honestly basing your vote on it seems like a really coarse way to distinguish between good and bad candidates...
I was referring to its use in the context of an election, which is often limited to the citizenry (in any democracy).
Also, where I live, public figures who use the word "citizen" to refer to ordinary people often don't use it in the literal sense of the word when discussing public-interest matters. They're often using it to emphasize the responsibilities and rights that all people have in relation to the broader society. In other words, where I live it's not often used in an exclusionary xenophobic way, but instead in an inclusive common-purpose way that emphasizes our shared humanity. The xenophobes here tend to prefer "taxpayer".
The irony, I guess, being that the xenophobes probably intend to raise a distinction better delineated by the word "citizen".
In the US some states or cities allow non-citizen legal residents to vote in some state and local elections (SF for examples allows non-citizen residents to vote for school boards)
