Another (more cynical) way to view the LibDems is that to win seats as... varied... as Brent Central/Redcar and Westmorland & Lonsdale/Twickenham at the same time, your only real electoral strategy is one of shameless local level populism, supported by very well targeted tactical votes and protest voters.
I doubt 99% of the Americans ITT understand the reference. Please clarify.
Brent Central is an inner city, ethnically diverse, London constituency.
Redcar is an industrial constituency in the north of England in one of the areas of the UK which has been struggling most economically.
Twickenham is a prosperous suburban area in west/south-west London.
Westmorland & Lonsdale is a largely rural constituency with an economy dominated by tourism.
That all these constituencies currently have MPs from the same party, and one which holds under 10% of the seats in the Commons, is not what you would expect.
