The former head of the Soviet Union Nikita Khrushchev observed more than 50 years ago that "politicians are all the same, they promise to build a bridge even where there is no river."
The observation was even more remarkable when you consider it was made by a man who knew little of democracy and a political promise was never required of him.
But in the lead-up to our election, promises are political currency even if the cheque after the poll has frequently bounced.
More than two years ago National was desperate to hold on to its Northland seat in a by-election until the campaign king Winston Peters declared his hand. Suddenly the electorate became a $69 million priority.
The man with the appropriate name for a Transport Minister, Simon Bridges, came up with a plan to solve a problem that had frustrated the electorate for years, the state of their bridges and he promises to replace 10 of them, even if one was just a ramp between two Kauri trees called Darby and Joan.
