With under a month to go before the first round of France’s presidential elections, there is still all to play for, with almost half of French voters still undecided. Arguably the most significant feature of the contest so far has been the almost complete collapse of the traditional parties. The incumbent president, Francois Hollande hasn’t even bothered to stand, so loathed is he by the public. His Socialist Party’s last hope, the “radical” Benoit Hamon, now languishes in fifth place according to recent polls.
