is there anything as pointless as arguing where the mythical "political centre" is? It's completely subjective and utterly meaningless.
In principle you can determine it statistically as the point where half the voters are to the right and half to the left. Of course it is difficult to make an operational definition giving the different views on what constitutes left and right and the number of relevant issues to take into consideration. Still, there are some general principles to go by and completely subjective is hyperbole. It is also a necessary analytical and descriptive tool regarding Western politics - also of some use when looking at much of Latin America and some Asian countries.
