it's all about turnout and walkovers and incentives (such as funding). in the u.s., there are seldom walkovers in every level of election because the major parties (two) have both candidates and funds to contest each seat, from district to city to county to state to national. it's a billion dollar industry here, and the victors normally get more funding and donations when they get elected. the smaller parties, independent, libertarian, green, etc. do not have the candidates and funds to compete, and they are often victims of walkovers in many elections, especially at the state and national levels. when an election is hotly contested, turnout becomes a factor. the sg system has taken walkovers and low turnout to a whole new universe. but it's true that walkovers are the result of too few oppo candidates (blame it on fear perpetuated by tyranny), too little funding, too much gerrymandering, fractional opposition, and too many constituencies in such a small fucking cuntry. and walkovers contribute to low total turnout. the u.s. system is fucked up, but the sg system is royally more fucked up. if this continues, it will lead to violence in the long run - too much pent-up anger and frustration among the male citizenry - perhaps a reason why china mei mei's are let loose on the island... to suck the angry juices out of these men.
