You say the Muslim population is 3%. I think it's way more than that, just by looking around. What percentage of eligible Muslim voters voted last election? Maybe 100%? What percentage of eligibile Christian voters voted? 35-40%, at best? Jihadi Justin Trufolo looks at these things and says, "ok if all Muslims vote in elections, then I'm going to get really friendly with them so they'll vote for me. There's no sense wasting my time with the Christians, if they don't vote."
Politicians are professional theives. They know election strategy. They study this, because these are their careers. If the Christians don't want Muslims in political power, then they have to get off their arses and vote against them. There's no excuse not to vote. The polling stations are in your own neighbourhoods, and there open from morning to night. Not only that, but they also had advance polling stations open for a whole week.
