Psp needs to have regional focus like how WP entrench themselves in the East. Other than maximising exposure, facilitate logistical support, it also to limit the impact of pap gerrymandering and the room to shift goalposts by contesting in close cluster.
Psp can't be fighting everywhere and scatter around due to limited resources and manpower. I can't think of anywhere better than the West where TCB has a higher likings and influence.
Places to target will be WC GRC, Jurong GRC, cck GRC, HK Smc. These were all places contested by 4th rated opposition. It will be easier for PSP to persuade those CMI oppositions to give way or if not easier get the upperhand in a 3cf setting.
Suppose if PSP have recruit more than 1k members and helpers, they can mount a serious challenge on 2 to 3 GRC plus a few SMC in the west. Strategically it also good for WP as it relieves pressure for WP in the East.
