Labour consistency and stability

This is the line pushed in at least one South Wales Labour citadel: that by voting Labour in year after year, there is no flip-flopping. The voter can rely on a consistent approach. Well, events in Glasgow give the lie to that one: http://www.bbc.co.uk/news/uk-scotland-glasgow-west-16964356. Local Liberal Democrats speak of "long-established fiefdoms", "a sense of anachronism and political decay", "all the real opposition has been within the administration", "They seem to have deselected about half their councillors. That rarely goes well!" and "the Labour group is a very nasty network of cliques, splits, personality clashes, sectarian and other issues".
