can pap survive a second barisan socialis?

this is purely speculative and unlikely to happen. but what if the pap actually splitted into two almost equal size parties competing for power? can the remnant pap under hsien loong weather such a storm? when the splintered section of the pap broke away in the early 60s to form the barisan socialis, lky was still a very young man, still trying to build up a support from a purely worker based party strongly under the influence of the pro communist group. goh keng swee, toh chin chye and rajaratnam were still newbies in the political arena. not much grassroot support. the real crowd mobilisers and organisers were those in the barisan camp, having organised themselves in workers and students union activities and in agitation for many years. the only strength on the side of lky was the british govt. the later did not really have a love affair with the english educated pap leaders but preferred them as the lesser devil than the pro communist barisan socialists. today, hypothetically, if choktong breaks away with half of the party members, including mps and ministers, the influence and appeals of the two camps will be quite equally matched in all quarters. it will be hard to find any difference between the two. it will be a choice between the popular choktong and a brand new young turk hsienloong backed by the experience of lky. in such a scenario, the opposition will suddenly be thrown into the limelight to share a coalition govt. parliament will not be the same again. we can expect a lot of fireworks and hopefully more quality and meaningful debates to compete for the people's votes. and we will see a situation when every grc and single ward will be hotly contested. no need to grumble about having no chance to vote or given no good choices. the aftermath, with only a single digit majority, or perhaps even becoming a minority opposition party, will pap then be able to reform and reestablish itself and return to its past glory? or with it whither away? this is highly improbable, but still a possibility. and will singapore collapse into oblivion and rejoin the third world?
