Presidential candidates should get ready for campaign of nasty business

Presidential elections now come with two great myths attached to them, writes Terry Prone. 

The first is that the capacity for ordinary Joe and Josephine Soaps to get nominated by local authorities is — like the very election itself — a profound exercise in democracy. The second is that we, as upstanding right thinkers, loathe and despise the nastiness that has come to characterise these elections.

The first myth starts with the belief that no incumbent president should ever be allowed to get away with a second term without having to fight for it and beg for it.
