Varadkar has to bring in a second FGer if being Taoiseach with a 60%+ approval rating means anything. At whose expense - logically you would think Burton, but the far left's national decline could see Coppinger join Gino Kenny in the rejects slot. There will be few if any FG transfers around to help Burton, but then she got elected last time without them. FF not exactly secure either - only 16% last time, and a very conservative pro-life TD in a suburban constituency.
In reality, 3 seats out of the 4 here could go any way between FG, FF, Lab, Coppinger and SF. Can't call it.
