For years, even decades, now Republicans have flaunted their ignorance to flout the Democratic Party by calling it the "Democrat Party". It's bad grammar, it's bad manners and it's a childish thing.
But it does bug many Democrats and lovers of English and civility. We don't have to just take it but we can respond with cutting humor: "The Republicant Party."
There have been some fine pushback as of late. The ever feisty Marcy Kaptur (D-Toledo) took Rep Rep. Jeb Hensarling (R-TX) to task for playing the silly name game. She politely and firmly pointed out we don't refer to the Republican Party as the "Republic Party."
Chris Matthews asked Republican Rep Daryl Issa (R-WTF) to "save that for the stump" with the petty name mangling. After Issa's trip to the woodshed, Rep Barney Frank joked he wouldn't hold it against his friend from the "Republicanistical Party."
Others have had fun with ripostes like "Rethugs" and "Repubes" and others. (I've always thought there should be some way to work "Reptilian" in there, as it's very appropriate).
But for my tastes nothing gets the message across like "Republicant Party." Republicant captures the stingy, austere, backward-looking orientation of this party who keeps demanding we follow their economic advice after they ran the country into the ditch.
Whenever I hear "Democrat Party," I will respond with "Republicant Party."
