DEMOCRAT / DEMOCRATIC, another county heard from:

[chiburb]

The 1993 Columbia Guide to Standard American English further reproves those who say "the Democrat party."

Democrat (adj., n.), Democratic (adj.) The proper noun is the name of a member of a major American political party; the adjective Democratic is used in its official name, the Democratic party. Democrat as an adjective is still sometimes used by some twentieth-century Republicans as a campaign tool, but was used with particular virulence by the late senator Joseph R. McCarthy of Wisconsin, a Republican who sought by repeatedly calling it "the Democrat party" to deny it any possible benefit of the suggestion that it might also be democratic.
