The biggest group of electors in France was recently cited by Juppé as being the centre. The problem in pretty much all the democratic world is that centre parties and candidates rarely if ever succeed. The candidate elections within the parties eliminate the moderates. Corbyn is a classic example, a party leader who represents the extreme views of committed party members rather than the left wing electorate in general.
Trump, Clinton, May, Corbyn, Sarko are not people many electors would choose as their leaders, people find themselves voting for them against their better judgement to stop an alternative they see as worse. The only candidates I have ever voted for out of conviction haven’t had a hope in hell of winning, Bayrou, Danny… .
I’ve had more socialists encouraging me to vote in the UMP elections than UMP members. The problem is that there isn’t one UMP candidate with a programme I’d give my name to – and I consider my views centre right, caring capitalism. I therefore believe in a progressive tax system, and equality in health and education. Being poor shouldn’t be viewed as a crime and poverty shouldn’t be a trap.
