Republicans and democrats are the same   stance: yes:
Yes it is...
There are several times "no" is the correct answer though; dictatorships have called themselves a republic (the example for nerds: the republic in star wars).
But in fact, are Republicans and Democrats the same.
In both forms the people vote for the person/persons they want to "rule" them, the people choose those who agree with them, the only difference is the different countries' way to do it.
For an example:
Denmark uses the way where the people (18+) vote for several people who they agree with the most, to become a part of the MPs where the elected people vote for laws etc.
USA chooses 1 president....BUT STILL: The people CHOOSE, and that's where they combine and IS the same, it's the people who vote and choose "the chosen ones".
