Most punters will vote for the resons they always have (likability, local work, geography), but there should be enough astute voters who fill the ballot to ensure that FF gets as few transfers as possible: how is this best done.
The only viable alternative coalition is Fine Gael and Labour.
FG on their own (if even possible) would be a scary prospect for anyone.
FG and SF simply would not work.
FG and Greens is a non-runner since the Greens won't have any.
FF and Labour is to be avoided at all costs.
So constituency by Constituency - what is the best tactic to apply?
eg Mayo - would you vote by preference with only one party:
FG weakest to strongest? Labour candidate, Mulherin, O'Mahony, Kenny, Ring, any independent, any SF.
eg Dublin North Central
FG No 2 (OMuiri/Breen), Bruton (who is likely to be elected but just in case), O'Riordan (lab), F McGrath, any independent, SF, Green.
eg Dublin Central
Pascal Donohue (Fg), Labour No. 2, Joe Costello, Maureen O'Sullivan, Green , SF, independents.
But there are some with different considerations, such as where reduction in number of seats:
eg Dun Laoighaire
Gilmore (to ensure he gets in a very tight constituency), Barret, FG no. 2, Labour no. 2, Cuffe, independents, Boyd Barret.
