Possibly because when someone calls someone a Republican it is using that word as a noun, but when they are using it in The Republican Party they are using it as an adjective. Mac OSX’s dictionary lists both those usages.
However, it only lists one for Democrat: noun. So calling someone a Republican is equivalent to calling someone a Democrat if you check the dictionary.
For all you get involved in political discussion here, colour me a slight bit dubious that someone how you’d managed for years to get the name of one of the parties wrong.
I’m sorry. I don’t believe you. I think you are backing down because you have been called on it.
Dude, I didn’t get called on anything. Have a look at what I said that got the OP’s panties in a bunch. I didn’t even SAY “Democrat Party” I said “people will vote Democrat”, which IS proper usage.
I voluntarily admitted later that I could potentially have used the wrong terminology because I honestly didn’t realize anyone would take offense over it. But I never DID use the wrong terminology.
You’re way off base.
We don’t; we use it as an intentional device to show them as the whiney pussy’s that some are.
We also misspell and use incorrect grammar to reveal them as elitists.
“People will vote for Democrats” is proper usage.
“People will vote Democratic” is proper usage.
“People will vote Democrat” is not proper usage.
Not at work, anyway! 
That last one always has irked me. As an earlier poster said, it’s using a noun where an adjective should be. “Democrat Party” irks me for the same reason. It just sounds ignorant.
I didn’t say they were poor and uneducated, I said they were childish and lacked the common sense needed to govern. Much of the rhetoric I’ve heard from the Tea Party has centered around complaining about taxes without proposing tangible spending cuts and generic flag-waving rah rah. No substance, no willingness to make hard, unpopular choices. (Which isn’t unique to them, of course, but when you’re trying to be revolutionary, it helps if you have something more to offer than lip service to ideals you don’t know how to execute.)
I agree that it’s rude, but that doesn’t make it unfunny. Incidentally, I don’t personally refer to any Tea Partiers as teabaggers. But I still laugh when I think about the origins of the movement, with cable news reporters trying to use the word “tea bagger” with a straight face. Comedy gold, I tell you.
My fucking god. How can anybody get their panties twisted over this? Of all the things people choose to get insulted about, this is the absolute pettiest. GROW SOME SKIN!
This is very very very very low on the list of issues that I care about. But the phrase “Democrat Party” grates on me. Partly because it’s wrong, partly because the meter is all wrong.
DEM-oh-CRAT-ic-PAR-ty is nice and poetic… accented and non-accented syllables intertwined. DEM-oh-CRAT PAR-ty, not so much.
I have no objection to “Vote Democrat” however.
Yeah! That broken rhythm right in the middle of the phrase really is annoying, isn’t it? Now that you point it out, I think that bothered me even more than the poor wording.
This is about #1437 from the top on the list of things that bug me. Sure, it’s childish, but that mainly reflects on them.
I’d happily give all Republicans and wingnuts a free lifetime pass on saying “Democrat Party” if they’d help pass a decent climate bill.
Now I may be totally out there, but I suspect that all of these things happen…
Folks mistakenly refer to the Democrat Party
folks intentionally refer to the Democrat Party
Folks mistakenly and incorrectly say thaey Vote Democrat
Folks Intentionall and incorrectly say they Vote Democrat
Folks intentionally say they voted for the Democrat.
In other words, while I am sure there are folks who say it in a demeaning way, most likely folks just say it without malice or intent one way or the other.
I realize it is a wacky theory, but there it is.
Calm down there, fella. 
We’re working on change we can get. We might be able to convince Republicans it is the ‘Democratic Party’ not the ‘Democrat Party’. Sad that we even need to have the discussion really, you’d think in over a hundred years they’d have figured it out already.
I think thus far it’s been proven we can’t convince them a climate bill is needed.
Yes, no, maybe? “Oh, I hadn’t thought of that”?
The Republicans are actually more fond of this trick as well, loving to quote the part of the constitution promising each state a republican form of government.
I believe we are expected to be stunned by the clarity of the insight.
No, I’m just waiting for someone to tell me why that road doesn’t travel in two directions.
Why don’t we just retitle this thread as Stupid Democrat Idea of the Day?
