In Australia we try to keep religion and politics separate but that has not always been the case. I don't know if religions have the moral right anymore to influence politics and public policy (certainly not after the Vietnam War) but they have always assumed that right.
As for paying no taxes, that has always been a sore point too. King John tried to get the Catholic Church to pay taxes. He felt that, after all the lives lost in the Third Crusade and the cost over run of this endevour, the Church owed his kingdom something. He was excommunicated and in order to rejoin the Church had to say he was sorry and not try to tax the clergy. And yes, back then there were arms of the Church doing quite well as businesses making profit. The Cistercian order (wool trade) were doing well and so were the Knights Templar (pilgrim trade).
In Australia, in particular Melbourne and Sydney, the Catholic Church representatives were against sending troops to Europe during the Great War. During the Vietnam War the Catholic Church was firmly in favour of sorting the communists out. They were even in favour of having the native ruler of South Vietnam be a Catholic in good standing despite their choice's open criminality. It was like appointing an Asian version of a Maffia don but it was done.
My advice is to vote for who ever YOU think will do the better job.
