If you do not know the difference between a Republican form of government and a Democracy form of government you should not be trying to discuss it. You certainly know little of the founding of the United States and it's Constitution.
Here you go again, wasting time (the result of blind ideology). I grabbed a definition of Republican govt. from google, why won't you do the same? (And we can do the same for "Democratic" govt.....and try to discern the difference). Answer, your argument would collapse in a heap of irrelevance, given we know - in the 21st century - what good governance (for a "more perfect union" and "the general welfare") ought to include, eg, an above poverty Job Guarantee.
Every single day. As Will Rogers was fond of saying: “I am not a member of any organized political party! I am a Democrat.”
