It is no more incorrect to say "Democrat Party" than it is to say "Iraq War." Nouns are routinely used to modify other nouns (i.e., "race car" and "sports car", not "racing car" and "sporting car.")
In everyday usage, it is perfectly normal to call a party full of Democrats a "Democrat Party." The modern use of the term is a grammatical force of habit rather than a deliberate epithet. The only people who dislike it are highly partisan Democrats (like Alben Barkley and GenMac) who should be worrying about better things, lol

Maybe you should educate yourself and get your facts straight before you write a smug, completely incorrect rant or try to come at me again, lol.
“Republican Pollster Frank Luntz tested the phrase with a focus group in 2001, and concluded that the only people who really disliked the epithet were highly partisan Democrats.[10] Political analyst Charlie Cook attributed modern use of the term to force of habit rather than a deliberate epithet by Republicans.”
Type in “Democrat Party” into Twitter and you’ll see that the only people who use it are far-right nutjobs like James Woods and Qanoners who spend all of their time on Twitter sh**tting on the “Democrat Party”
