Both polls published (or leaked) today indicate a drop in support for government parties.
Both also indicate that FF are ahead of SF - but according to the Red C one at least not by much.
It's possible that FF could be a couple of points ahead of SF & still come in behind them in terms of seats - especially with so many Independent transfers likely to be around. And it's also quite possible that SF will overhaul FF before the next GE.
With a FF/SF/Ind government becoming a distinct possibility it is possible that Adams could be the leader of the largest party in government. Could he become Taoiseach, or could something similar to Richard Mulcahy withdrawing as leader of Fine Gael in 1948 happen. That was because Clann na Poblachta wouldn't join a government led by him?
