Then be a private activist. Give the SDP to real people who can gather support and win elections. Do not say that the PAP is to blame for every opposition failure. SDP is the ONLY party to have the largest fall in the number of votes, to lose three good seats in parliament every since this IV drip hunger strike Dr. took over.
For more than 40 years, PAP has relentlessly pummelled the oppositions using legal means illegally, to the extent that the oppositions are about to go extinct. The huge number of uncontested seats is a result of LKY's brutality against his political opponents and opposition parties.
Election results are a poor guide to judge SDP as PAP is notorious for manipulating the electoral process: gerrymandering, threats against voters, lies and slanted articles in the 154th to character assasinate political opponents, withholding of tax payers money for HDB upgrading from opposition wards etc.
