Negative Voting : Are you + about it???

With General Elections around the corner,all the major parties have launched their campaigns in cyberspace by having their sites.Even CPI(M) which is against American policies has got a site of its own on internet(an invention by an American). It is not just politicians but Netizens, too, who are busy launching campaigns in cyberspace.Among all those campaigns the one that caught my attention was Negative voting.This is the latest buzzword on social networking sites and blogs. So what does it exactly mean.It is an option for voters to reject all candidates in a particular constituency.
