I'd say they'd turn into a pressure grout/movement rather than a political party. As a party they are finished. The Green candidate in Galway is a decent man but totally naive, I'd say the whole lot of them are like that, well-meaning people but totally out of step with what people want.
There's another story about some journalist looking into the back of his car and seeing a whole load of blank placards. Clearly he didn't know which protest he was going to next so was keeping his options open!
Richard BB is a 'celebrity socialist', the acceptable face of the far left. There was a joke going round that if he gets into the Dail he will be in for a shock, as he finds out that you're not allowed use a loudhailer in there!
About 12 years ago I was at a party in Galway in Ming Flanagan's flat, there was lots of reggae music and dope being smoked. At that stage what odds would I have got that one day this guy would sit in Dail Eireann!
Unfortunately Grealish will likely get in again, the worst sort of old style politician, completely lacking in ideas, policies or principles, elected by his neighbours because he's a 'decent skin'!
If nobody voted I guess the candidates themselves would at least vote and so would their families and the quota would be so low that that would be all they needed to win, whoever had the biggest family in other words.
RE: new government
Maybe they're also worried about contagion!
