In the past the Liberal Democrats - being a "Liberal" ( as the name suggests ), kind of political party have had the indictment of being a bit soft in certain lines they take.
Nowadays and because the New-Labourites have lurched so far to the right they are starting to look like the only party that gives a damn about the ordinary man-in-the-street.
I am sure that they will hammer that point into us in the weeks approaching the general election and if they don't I think they will have missed a trick.
All political dogma evolves to suit the prevailing conditions and I am sure that the Liberal Democrat dogma will do exactly the same as the rest in order to get back the political power they once had in Britain.
