I'm far from an etymologist, and I can barely speak English as it is; this is the best I could do:
The English word election is ultimately derived from the Latin language - electus, the past participle of the verb eligere ("to chose"). The adjective form (elect = "chosen") found its way into the English language sometime before the 15th century; the word election came into being sometime around the 16th century.
The English verb to vote stems from the Latin verb vovare ("to vow"), and its past participle, votus ("desired" or "vowed"). Its use as a verb (back then retaining its meaning of "to vow") was confined largely to Scotland until the 17th century.
"Vote early, and vote often." --Richard J. Daley; Mayor (1955-1976), City of Chicago, Illinois.
Today is the general election for King County, in the lofty State of Washington. Polls close at 8:00P.M., Pacific Time.
Do it.
