1. Did I consider the legal implication of being actually at the precincts observing how election is being conducted? You need clearance and approval from COMELEC officials to do this kind of method.
2. How can I be at so many precincts at the same time? If I would stay only in one precinct, the result might be too narrow to have significance.
3. Would your effort in conducting such a study matter to the COMELEC officials? Would the possible result of your study can actually change the conduct of election system in the city?
4. Will the result of your study be useful, if it only covers Angeles City, or you observe only one precinct?
5. What would the poll watcher say if they know that you are there to observe, when you don't represent any candidate?
6. If you ask for the help of research assistants who would be observing during the election day, the result would still be more accurate if you, as the researcher, were actually the one who conducted the observation.
7. FGD, in general, may be used to verify information gathered from the respondents.
8. FGD is easier said than done. It's very hard to gather people who don't even know each other, or who don't even know you as the researcher.
9. Giving your study geographic depth could give it more significance.
