Those Joo Chiat residents won't be able to offset the larger numbers in the newly added Chai Chee HDB estates, aka Boomer Central. You know how this group swings.However, the trade-off is that the new East Coast GRC is now very winnable for the WP, especially because it contains the former Joo Chiat SMC, which is historically pro-opposition.
The Changi parts of East Coast have been carved out and merged with Pasir Ris but those areas were less accessible anyway and with their removal, the WP can focus their campaign on a smaller area, which in turn makes it easier to reach out to as many voters as possible.
