A demagogue is a political leader in a democracy who gains power by appealing to passions, prejudices, and the ignorance of common people, tending to undermine democratic procedures and rules of law.
Their history goes back to Ancient Greece.
That would have been in the days of yesteryear. Now we have Panderers, Snake Oil Salesmen and creeps with qualities so cheap that they are mere pretenders to the throne of demagogary.
Pimps.
Trump is a pimp in an expensive suit.
Obama.

All politicians are demagogue's to some degree, but the one who stands out as #1 would have to be Obama.
Obama calling anyone a demagogue is the classic tea pot calling the kettle black, lol.
Now that's funny!
Obama
Of course. Obama should not throw stones in that Glass White House, He is just more civil about his demagogary, but he is spot on regarding Trump.
I just think Trump is a demagogue on steroids.
