A number appear to be pro-Democracy parties.
If you think about it they must all believe in the principle of Democracy, in its current form at least, or why would they bother to register with ElComm?
It suggests that there is scope for getting people from many disparate groups under one roof for the cause of democracy itself as defined in 1902 (Nuttall's Standard Dictionary):-
"A form of government in which the supreme power is directly or indirectly lodged in the hands of the people."
Even in Parish & Town Councils supreme power is lodged through indirect democracy (representative democracy) and Direct Democracy (referendum) is rare. Even when used it is subject to unfair competition with the Government and its agencies & associates usually spending more money and time (media) on their preferred choice.e.g. UK 1975 referendum on the EEC.
The first Irish Lisbon Treaty referendum was a rare win for the opposition, and having travelled to Ireland on holiday on voting day (purely an accidental coincidence because we booked the ferry months before the referendum was announced), I revelled in the aftermath. The Irish Government and media was in apoplexy - something to savour - and the coverage was like drinking free, rare wine. Delicious!
