Latin candidatus, from candidus (glistening white, from candere, to shine): office-seekers wore the toga candida, artificially whitened with chalk, to signal integrity while canvassing the Forum. The same candere root gives candle, candor, incandescent, and candid, the whole family trading on visible brightness as moral proof.
The irony everyone notices: candor and candid share the root with the profession least associated with either. The toga was spin from day one, a manufactured look of purity for a process that has never been pure.
Candere's core is not color but heat, glow, burn: candid camera, incandescence, incense. The candidate is, at the root, someone set on fire for public display, which campaign staff will confirm is exactly how it feels.
Has a candidate ever survived contact with the office dressed the same color?
