Being a cynic, I assume that some start with a mild veneer of wanting to do good which is easily shed as the lure of imagined (*) power tempts them to trade fragile fragments of morality.
Others have no doubt from the start whose interest will direct their political careers.
(*) Imagined because once they've been assimilated into the swamp they find that they are controlled by the Borg mind and can influence, let alone control, very little indeed except whether to wear a jacket over an England shirt and whether to wear a hard hat as well as a hi-vis jacket. Thus the would-be mighty fall as the Ides of March grind the sausage-meat of politics.
