It would be interesting to be a fly on the Martin/Duffy kitchen wall at breakfast time to puzzle out this one. Catherine Martin is for this coalition deal, while her husband and Dáil colleague, Francis Noel Duffy, is against it.
Dublin-Rathdown TD Martin is deputy leader of the Green Party, an opponent of even entering coalition talks, but leader of the party's negotiating team.
Duffy, newly elected TD for Dublin South West, was one of the three party TDs who abstained on this deal.
During the six hours of the party's video conference, he stridently explained why he is voting against the coalition deal and urging fellow members to follow suit.
Ms Martin banished some residual doubt about her approval of the coalition project by strongly endorsing it in a move that could yet prove pivotal in this membership approval process, which requires a two-thirds majority. There were, of course, caveats that will raise eyebrows in Fianna Fáil and Fine Gael.
Notably, she urged a rolling review of progress, which could be updated every two months. She reasonably expects a big review in December 2022, when Micheál Martin and Leo Varadkar respectively step out and then in again. That would surely happen automatically - if we get to government and it lasts.
Suffice to say that the other parties have long been amazed by the level of membership consultation that goes on in the Green Party.
In October 2009, after two and a half years of coalition with Fianna Fáil, a significantly revised government programme negotiated by the party principals had to be again voted on by the party membership at a special convention, just like the original one in June 2007.
There was also a membership vote to endorse the establishment of Nama.
The Fianna Fáil negotiators and leader merely ran the new programme past their own parliamentary party for a rubber stamp. One key Fianna Fáil figure lamented the bugbear of having to put every other issue before the Green membership.
Often, as contentious issues arose or there were points of internal tension, the party leader wrote a circular email letter to the members, laying out the facts. The reality is that it led to more cohesion, and in very difficult circumstances, that coalition held together for three and a half years, a span that was beyond the average at that time.
The reality is that the member consultation the Green Party was doing in 2007-2011 is now being done, to a lesser degree, by many of the other parties.
Fianna Fáil now has 'one member, one vote', which is being used for the first time.
Fine Gael has a much paler, more manageable version from a HQ standpoint, which gives members 25pc of the say. They give the most volatile element of the membership, the councillors, just 15pc, with 10pc going to the national executive, but the lion's share, 50pc, is reserved for the TDs, senators and MEPs.
And while Green Party politicians such as Dan Boyle and Ciarán Cuffe enraged their Fianna Fáil partners by using social media to voice dissent last time, now the vast bulk of politicians do the same.
So, for now the Greens are the most consulted members - but that is changing.
