Firstly, I don't think a Tyrone GAA board is an appropriate place to bring up this discussion there are main discussions for non GAA related issues. But now you mention it I shall reply.
Secondly Sinn Fein are only important to the DUP so that they can prop them up and allow them to continue to walk all over our community. Previous to this election Sinn Fein allowed the DUP to march all over them, I will be interested to see how many times they fold this time around. Sinn Fein knew about RHI approximately February but it was Spotlight that exposed the DUP, SF were happy to back their mates in government. SF continued not to criticise DUP around this scandal in the early weeks of exposure again having private meetings with the DUP.
They wont go into government until Arlene steps aside, Until there is an Irish language act, Until there is equal marriage. These are all promises Sinn Fein have made to their electorate.
