actually, in practical terms, I don't know how this can be done.
We have no Christian party in Singapore. All political parties
comprise of people of all religion. I am sure the PAP Christians
debated a great deal, behind closed doors on these issues.
Unfortunately, in a secular government, decisions are made based
mainly on profit or for the "greater good".
to say that we should not vote for "for christian politicians who
do not take a stand against abortion, or worse still, support it,
is to cause a grave scandal to other believers." is wrong, we might
as well say that the government is not against divorce.
