I believe that Low did tried to grow opposition in numbers.
In GE 2001... WP fielded 2 candidates
In GE 2006... WP fielded 20 candidates
As for reaching more people & engaging them.. it will depend on whether the people accept the opposition parties as part of their lifestyle. For example, in GRC like Tampines & Pasir Ris-Punggol where I stayed & worked there for many years.. people there dun like opposition members & unlikely want to listen to their talking
Not enough other races members, will lose these races votes.
WP seems like a chinese clan party.
