Peter, please don't use Democrat Party, it's something the right has used as an insult.

That's something I started doing many years ago out of a deference to the idea that Democrats did not have sole possession of democratic principles. You've got to remember that I'm a life-long Republican who left the party after the 2016 primaries. The idea that my party could even entertain such a knucklehead as that forced me to leave. And not wanting to be wishy-washy about my denouncement of the Republican party, I registered as a Democrat rather than an independent or some other third (or fourth or fifth ...) party.

Perhaps naively, I still hold on to the hope that the Republican party can reform themselves and return to being an actual political party rather than a personality cult.

Having said all that, I see your point. And having checked that the national party refers to themselves as the "Democratic National Committee", I will start adding the -ic suffix back on when appropriate. As you said, right now, only one party is holding on to democratic principles, and that is the Democratic Party.

PS
As a side note, I enjoyed a piece on The Daily Show a couple of days ago where the MAGA faithful were spouting off that the US was a republic and not a democracy. They seem to have completely forgotten their high school civics classes where we learned that the USA is a democratic republic. Yes, it's a republic in that we elect representatives who are supposed to use their own judgement when deciding what is best for both their constituents and the country as a whole. (Not that either party has done that very well over the last few decades. What is best for the representative seems to be a significant factor in much of the decision making.) But those representatives are elected in a democratic process, where every person gets a vote. And we'll completely ignore the historical usage where even this subtle difference may not have mattered and the two terms were used almost interchangeably.
