Nothing wrong with that. If his ward is contested by those mosquito parties, he should of course vote for PAP, like what I intend to do on polling day.
I consider myself to be a staunch opposition supporter, but not mosquito party supporter. The only opposition party worth voting for is the WP, and maybe to a lesser extent the PSP. I think we need more opposition to get into parliament to speak up for Singaporeans, but at the same time, we need a strong government with proven track record which is the PAP.
I live in Limbang, Marsiling-Yew Tee. Lawrence Wong is my MP. I will be casting my vote for him, even though I sincerely despise the PAP for various reasons like POFMA, Reserved Presidency, and ownself check ownself. I am 100% against one party dominance. At the same time, it is critically important that we do not vote the current ruling party out of government, and I will not vote the PM out. I am voting for Lawrence Wong and his team, so hopefully more elected opposition MPs will get into parliament and grill the PM and his cabinet, so that they'll work harder to earn the support of Singaporeans.
I encourage people living in wards contested by Worker's Party to give the Worker's Party a chance, vote for them. We need a strong and credible opposition party in parliament. It's time to put an end to one party dominance.
