Currently the need to establish a core vote seems, akin to motherhood and apple pie, to be so obviously a good thing that it cannot be questioned. However, at the risk of upsetting friends and others alike, let me raise some concerns.
Firstly, there is the simple truism that in a First Past the Post system you cannot win by playing to your core vote, even if you have one. That is a lesson Republicans and Democrats in the USA have to relearn from time to time. It is a lesson the Conservatives had to learn after Thatcher when Ian Duncan Smith, Michael Howard and even William Hague pandered to the right. It is a lesson Labour had to all so painfully learn after the Bennite manifesto of 1983 dubbed the ‘longest suicide note in history’. The Corbynistas may have to learn it all over again.
Secondly, how long does it take to ‘build a core vote’? The affluent Conservative core vote has always existed with the addition of a section of the working class following astute action by Disraeli from his passing of the Second Reform Act of 1867 onwards. Labour’s core vote –primarily lower income, urban and unionised- was uniting behind them over a century ago; especially after the Liberal Party collapse left the field entirely clear after 1922. How long would it take the Liberal Democrats to establish the loyalty of a similar core vote and at what cost? Some have suggested we should pursue our core even if it puts off ‘mainstream’ and/or floating voters. Really? We should fight elections not to try and win but to try and build a long term core vote?
