Democratic Semantics

In this year of 2006 there are two predominant political parties in America, Democrats and Republicans. Interestingly our form of government is a republic, not a democracy. But that is begging discussion at a later time.
For now, let’s define “semantics” courtesy of Merriam-Webster.

"Main Entry: se·man·tics Pronunciation: si-'man-tiks
Function: noun plural but singular or plural in construction
1 : the study of meanings
a : the historical and psychological study and the classification of changes in the signification of words or forms viewed as factors in linguistic development
b (1) : SEMIOTIC (2) : a branch of semiotic dealing with the relations between signs and what they refer to and including theories of denotation, extension, naming, and truth
2 : GENERAL SEMANTICS
3 a : the meaning or relationship of meanings of a sign or set of signs; especially : connotative meaning
b : the language used (as in advertising or political propaganda) to achieve a desired effect on an audience especially through the use of words with novel or dual meanings"

With this in mind I have a question or two, or more. Why do we often refer to Democrats as members of the Democratic Party? Do we speak of Republicanists? How about Republicanics or Republicaniacs?
Hell, even my spell checker can’t abide that!
Here’s my theory. We have become so enamored of our so-called “Great Democracy” that we have forgotten the meaning of the words. “Democratic” sounds so warm and fuzzy, so nice. Bull!
So, please, for the sake of the sanctity of the king’s English language, let’s forego the use of the ‘Democratic Party’ in favor of the proper ‘Democrat Party’.
It will make me feel better. And Democrats are all about feelings.
