Is Democracy a bad idea?

Look at me! Look at me!

Aren't elections just popularity contests where the one with the greatest media exposure (and cash, to pay for that exposure) ends up winning? Isn't 'democracy' basically mob rule? Are ordinary schmucks really qualified to select the person or party that will in the end up running a nation? I mean, just look at those people in the photo there. Do you think any one of them is even qualified to run a chook raffle?

Okay, a few (simple) definitions:
Democracy - rule of the majority via representation.
Republic - non hereditary head of state, referred to as a president.
Monarchy - hereditary form of government, that can be either absolutist or democratic (ex. Spain, Denmark).
Dictatorship - a tyrannical government that acquired power via brute force, and basically does what it pleases, and this form of governance can be established as either a monarchy or a republic (but it's almost always a republic).
