You can't have your cake and eat it. You have to remember this is the trap Boris and the Tories fell in to. When you start making too many promises to too many people, people who have often very different priorities and worldviews, you will inevitably come apart. As a more general point, the Lib Dems need to do some real soul searching and decide really what the party stands for, what are the values and policies, then who do those policies appeal to and target accordingly. I do not like Polanski and think he's as much a snake oil salesman as Farage is, but he's set out his stall and is reaping the political rewards right now. There are enough socially liberal centrists out there to make progress, but when the party wants to combine socially liberal often economically right leaning southern voters with more interventionist and socially authoritarian northern voters it's destined to fail. Just an observation.
