the objective is around 100 000 since in the last elections FPM got around 200 000 votes.
(i'm considering the other 100 000 dont have facebook, not because FPM lost popularity).
If we can achieve that number than we can consider we won the elections.
However there is one problem which is the fact that teenagers can join. That can flaw a little bit the numbers but it's ok.
Out of 30 people in my family who will vote for FPM, less than 10 use Facebook.
So let's not throw big numbers like that
What is the biggest Lebanese group on Facebook and how many members are in this group?
