Will the Green Party leadership election provide a way to keep the party's coalition dissenters on board? Or will it fuel a dangerous Green anti-Government rump?
Those are the questions many of the Green Party's Government partners in Fianna Fáil and Fine Gael have been taking from this marathon, but well-mannered contest between the leader, Eamon Ryan, and his rival and deputy leader, Catherine Martin.
It is largely forgotten now that last time the Green Party entered government in 2007 it had also had a leadership contest. It was caused by its leader, Trevor Sargent, keeping an election promise and quitting the leadership rather than take the party into coalition with Fianna Fáil whom he had castigated.
And on July 17, 2007, four weeks after 86pc of Green members backed government with Fianna Fáil, the result showed a 2:1 majority for the pro-coalition party chairman John Gormley over the vehemently anti-coalition contender and former MEP Patricia McKenna. At the time, Gormley insisted the leadership vote was not about the Greens being in coalition as that question had already been well and truly settled.
But the one-in-three vote for the perennial dissident, McKenna, was seen as a kind of choke-chain being placed by party members on the Greens' parliamentary party lest they become too cosy with their Fianna Fáil coalition partners.
Many details are different 13 years later - but a similar dynamic is at play today.
So, will it be the Greens' "coalition nice cop" Eamon Ryan? Or can the party's "coalition nasty cop" - Catherine Martin - cause a major upset?
The reality is that Ryan will win this one by some distance. He took a very battered party in 2011, when they had no State funding and just three councillors, and devoted the next nine years to its re-generation.
By February 2020 the party had 49 councillors and 12 TDs, making him its most successful leader ever. This contest, required by rule, should be a technical exercise long ago resolved.
But politics are sometimes complex and the Green Party really is different. Catherine Martin has a considerable bank of members' support and has put in a very strong campaign. Martin is also a formidable candidate, and she was along for much of the party re-building having taken over as deputy leader in June 2011. Her stance during the weeks of coalition talks was seen as more strident and her leadership campaign echoed that with warnings of a potential withdrawal from government.
Her supporters suggest that the bar she has to rise above here is the 24pc of party members who voted against coalition last month. Prominent members of the "No coalition" campaign were her most vocal supporters.
So, the only issue here may be how many of the "soft pro-coalition vote" she can muster. If it is high the coalition partners will take note.
Any way you look at it, just like that forgotten leadership election in 2007, this contest is still about coalition.
