Another poll (the last?) provides the basis for this further update.

This morning's poll from RED C/Paddy Power for which polling was done Thursday to Sunday confirms the upward trend in Fianna Fáil, the downward trend in Sinn Féin and the refusal of Independents to "fade away" as the real decision is imminent.

Again I provide an additional Poll of Polls based just on 2016, the 15 polls that have been conducted since the start of January.

This series is of course much shorter, and the final outcome is much more dependent on the last few in the series than is the case with the more comprehensive set used.

Seat predictions based on either approach to the Poll of Polls leave the Government well short even of 70 seats, but both would give Fine Gael and Fianna Fáil a clear majority should they agree to combine in government.

The shorter time span is better for Fianna Fáil by four seats and worse for Sinn Féin, also by four seats.

Labour may still be overestimated on 12 seats given only 7% of the vote.

My model gives them a bonus of four seats relative to their size, because that is what has happened consistently since 1981, but it could be different this time and the 12 is certainly an upper estimate.

Based on 2011-2016 polls

Based on 2011-2016 polls, the % of votes is: Fine Gael 28%, Fianna Fáil 20%, Sinn Féin 17%, Labour 7%, PBP 4%, Social Democrats 4%, Green Party 3%, Renua 2%, Independent Alliance 3% and Others 14%.

Seat predictions are: Fine Gael 53, Fianna Fáil 33, Sinn Féin 27, Labour 12, PBP four, Social Democrats five, Green Party two, Renua two, Independent Alliance three, Others 17.
