Isabela Gubernatorial Elections 2010

By Mikko Tamura

The Isabela Gubernatorial Elections of 2010 can be contested to be one of the most tight and controversial provincial elections in the country. With the small margin of the winner (Dr. Faustino Dy III) of less than 2% to incumbent governor Grace Padaca, it has been root as to which different allegations have brought up. Former Governor Padaca was able to win 2/3 in all of the municipalities, but Dr. Faustino Dy III was able to garner enough votes from the urban centers (Cauayan City and Iligan City) to defeat Ms. Padaca with 3438 votes.

This event has caught my attention and interest to create a map in order to provide information to the people of Isabela and those who are also interested in mapping political geographies. This map can be an aid to those who want to view the phenomenon in a geographical perspective. These maps can be a possible tool in order to better plan out campaigning strategies so that candidates may better prepare for the next election.


  • To create a map that will be able to provide information on how the distribution of votes per municipality in the Isabela Elections of 2010.
  • To present the winner by municipality in the 2010 Isabela Elections, in order to identify the weak and strong territories for the candidates.


  1. Data Collection:
    1. Data:

i.      Comelec Official Results for the Province of Isabela (Municipality level)

ii.      Comelec Voter Turn Out for the Province of Isabela (Municipality Level)

  1. Frames:

i.      PHL_Provinces.shp – Shape file for the Philippines and the Province of Isabela

ii.      PHL_townscities.shp – Shape file for the municipalities of Isabela

  1. Processing:
    1. Gather needed data and input into excel. Consider the winning candidate per municipality and represent it with 1-Dy 2-Padaca 3-Uy 0-Chartered City. Apply a thematic categorical symbology. I have used the actual color in campaign for each element.
    2. Tally the number of votes casted per municipality and apply an increasing shade intensity to identify that the darker the color defines the greater number of voters.
    3. Consider essential municipalities and provide labels and descriptions; e.g. Cauayan City.

I had a hard time thinking how am I able to present and merge the 2 maps (voter density and winners) in one map. A dot map over a thematic map is a bit risky and congested. That’s why I have decided to present it in 2 maps. In addition I have a hard time organizing and choosing viable data to be presented, whether a pie chart or a table would be necessary. I also had a difficult time in use of legends, for ArcMap is not capable of doing a continuous intensity chart. I used Microsoft Word in order to fix this problem.  In addition, due to the limited space, I would like to add other important features like labels of the municipalities and the actual election results table.

Words from the Cartographer

It has been my passion as to which to recreate and revolutionize the method in map making political geographies. Interestingly, it has been a fruitful experience for me to learn so much from this subject. I have seen a different perspective in creating new tools for others and at the same time comprehend the science under this beautiful art. I would like to recreate election maps and present as much information in a single sheet of paper for others to appreciate and comprehend.
