A good politician is a good negotiator – at least you could assume that. After all, negotiating is the daily bread of a politician – especially if s/he operates on relevant interfaces. Legislative decisions, foreign policy aspects, internal security, social benefits or economic support – the list may be continued arbitrarily, whether in dialogue with company representatives, fellow party members, government partners, committee members, EU members or decision-makers in the local constituency. A good outcome of a negotiation can be crucial for a member of parliament and decide whether s/he will be re-elected.
