that is actually a great suggestion....if you do not pay for it you get no say in it...maybe an IQ test or a general political test that would weed out the knee jerk voters and idiots...the politicians would be forced to appeal to a more intelligent audience...
also drug testing for those who apply...nothing against druggies legal or not...but if you are on pills/blunts/lines/pipes then you should stick to that and not bother with politics...
the other great flaw is the media...
media grading according to bias would be a good course of action...also grading of individual reporters and their bias...just like movies are rated PG or whatever...this TV channel for example has low scores based on bias towards political party x and this reporter is a well known bullshiter....mandatory grading and ranking like for food with the score in the bottom left part of the screen like "reputation" quantified in to a 1-5 rank ect...
grading of political parties as well...lets grade the democrats and the republicans and the whoever like IMDB movies...based on last elections promises vs. actual accomplishments...would make them more responsible in the pre-election period and more diligent in the post election...accounting for politicians
banning religious propaganda from politics would be huge...until you can prove your imaginary friend in the sky, or find some reason why thor and spiderman are a less credible story, lets leave politics to people who have a firm grasp of reality and do not need their safety blanket to manage life's troubles...you are free to practice your paper cup worship at home, but a fair suggestion would be to ban politicians from mentioning religion during their campaigns...
the above would fix democracy a lot...the current model is too stick and carrot and there are many jack asses with voting "rights"...voting is not a right, like a driving license is not a right...both are equally complex and are a privilege...if you really want in, nothing is standing in your way, pay taxes , learn the fuck about politics and take the test and viola!...
