Setelah sempadan kawasan undi diumumkan, Ng mengatakn yang parti itu mungkin bertanding di Mountbatten SMC. Namun akhirnya, Setiausaha Agung Chia mengumumkan yang akhirnya, parti itu tidakakan bertanding pada pilihan raya ini untuk mengelak dari bertembung dengan parti pembamkang yang lain. Walaupun begitu, Ng masih berhasrat untuk mengambil bahagian dalam pilihan raya ini dengan bertanding di bawah parti Perikatan Demokratik Singapura di Kawasan Undi GRC Tanjong Pagar. Namun disebakan lewat menghantar borang semasa Hari Pencalonan, pasukan SDA ini tidak dibenarkan untuk bertanding. Oleh itu, GRC Tanjong Pagar menjadi kawasan undi yang tidak perlu dipertandingkan dalam pilihan raya ini.
By the time the electoral boundaries were confirmed, the party had split over whether to contest or stay out. Mr Ng indicated that it will contest some SMCs, in particular Mountbatten SMC. However, secretary-general Mr Chia Ti Lik announced that the party would not take part in the election to avoid contesting against other opposition parties in three cornered fights. Mr Ng, with some members from the [[Singapore Democratic Alliance]], then prepared to contest in [[Tanjong Pagar GRC]] as independent candidates. They failed to do so as they were late for nomination by 35 seconds. This resulted in Tanjong Pagar GRC being the only uncontested constituency in the [[Singaporean general election, 2011|2011 election]].
Bendahari Mansor Rahman pula meletak jawatan dari parti Socialist Front dan menyertai Parti Reform supaya dapat bertanding di [[Ang Mo Kio GRC|Ang Mo Kio GRC.]] Namun, dia tidak menang. Selepas pilihan raya ini, parti Socialist Front tidak lagi aktif.
