my Muslim brothers will not shout here o....but am asking, can a Christian be elected also in Saudi Arabia, Pakistan, Indonesia, UAE or even Iran?

Of course they can be elected in Indonesia. Well in fact, the number of Christians in Indonesia is one of the largests in Asia. Its Christian population is 4 times larger than the whole Singapore's population.

In the current cabinet of Indonesian government, there are 7 ministers with Christian background. And hundreds of Indonesian mayor, governor and people's representatives are from various religions beside Islam.
