"Great question! It's a common misconception because both forms of government involve representation and the rule of law. However, a constitutional republic, like the US, has a constitution that limits the powers of the government, whereas a democracy is majority rule. Understanding the differences is key to preserving our democratic values. #EducateYourself"

Perhaps some people in power might find it politically expedient to do so: If they can ingrain the idea in people that a 51% majority can vote to infringe the rights of the 49% minority they can increase their power and control

Yeah but its both isn't it?

Democratic Republic would be a good term for them.

If power hungry psychopaths can convince the populace that their rights aren't granted by God, but by popular vote, then shifting public perception by controlling the media and shifting vote totals by controlling the vote count is all it takes to give power hunger psychopaths "moral" cover to infringe on our God-given rights.

It's not a misunderstanding, it's deliberate, pathological brainwashing.
