Dear Dr Koh, Punggol East residents care only about "day-to-day miniscule issues" and not national issues?

Yahoo! News Singapore, 23 Jan 2013
People’s Action Party’s candidate for Punggol East Dr Koh Poh Koon brushed aside the jabs made by the Workers’ Party against the ruling party in a rally Tuesday night.
“This by-election is about finding the best person to serve the residents needs. It’s not really to better the interest of another political party. We’ve got to be clear what the election is about,” Koh said when asked for comment on calls to support the opposition in Parliament by putting more opposition members there.
Koh declined to comment on the opposition highlighting national issues but emphasised that his focus is on what the residents of Punggol East personally need day-to-day.
