Yep, expect more of the same as the calls for a border poll become stronger. But thems not the rules.
Hypothetically if there was a united Ireland tomorrow what would be each Parties % representation in any Dail. Obviously there would probably be an amalgamation of parties. But as it stands now what would it be?
This is a good article which breaks down roughly what you could expect. Note this is before last years election so SF would be higher based on more recent figures.

SF will be the political vehicle to get a United Ireland. Where they go from there will be anyone's guess. They will have their go at power soon down south, they are blessed on that front as they can hardly do worse than what FFG have presided over the past 15 years or so. There is going to be an assembly election either this year or next, there's a very strong chance SF will be the largest party after it. There could well be a general election sometime next year down south and I think it's inevitable that SF will be the largest party down south and likely to take the lead role in govt after that.
When or if that happens is when the wheels will be in motion for a border poll, there are plenty political factions on this island on both sides of the border opposed to that poll but I think the will is there with the people for it.
The article Snapchap posted perfectly displays the duplicity by Martin and FF. It's obvious to anyone who has a brain than they do not want reunification as it takes away their grip of power they are desperately trying to cling onto, the prospect of reform makes them quiver in their boots and anyone who buys the strawman arguments about respecting unionism really need to give themselves a shake.
