That's EXACTLY what just happened in the US.
You don't have to 'debate' it, just watch and see your answer unfold.
The only thing Trump is open about is that he lies repeatedly. I, too, have said that no-one can accuse of him lying about what he is, the problem is that thanks to Reagan absolutely fudging public education back in the day, you have an angry and relatively uneducated swathe of people who have been fudged by the promise of trickle down economics, see every Democrat as a communist dictator, and thus end up seeing silver tongues billionaire liars and thieves as their saviours. Thus a vote which has effectively ended 'democracy'? Is it 'undemocratic'? THAT depends on your definition of true democracy!!!!
Perhaps the more interesting debate question is whether lying matters in a free society?
