SG Election Map and Intro
- detail verison: http://www.eld.gov.sg/elections_map_electoral.html
- basically, each region need a election for member/members of SMC and GRC
- SMC means single MP (member of parliament) representing the interests of the regional residents
- GRC means multiple MPs (as a group of 3-6) representing the interests of the regional residents
- which region use SMC or GRC depends on region size, also as reflected in the election map
