Liberal Dirty Tricks?

Having tested the water, local Liberal Democrats are now starting to pre-register for Spelthorne’s Open Primary election next month.
The Conservatives are relaxed about this because there has rarely been any effective minority party manipulation of primaries in America, where they are commonplace.
In a secret ballot voters realise they are choosing the person that could well become their next Member of Parliament, and are therefore careful to go for the very best person.
Besides the Liberals’ attempt at dirty tricks in Totnes last August backfired spectacularly, when the candidate they backed came last!
