Micheál Martin could be forgiven for succumbing to the Monday blues today - just pulling that duvet back over his head and staying in bed. Critics might say it would not be such a bad political strategy on grounds that it could do least harm.
Both the party leader and Fianna Fáil are stricken with a very bad case of "'tis worse things are improving". Bad enough to score a disappointing 22pc in the General Election on February 8, but the opinion polls since have logged its fortunes as going down, down and down again.
Yesterday a Red C poll for the Business Post put Fianna Fáil on 10pc - a ranking never, ever, seen anywhere before.
Regional breakdowns of the poll come with a certain health warning - but there will be alarm its support in Dublin is put on a lamentable 4pc. That of itself could have an impact on the leadership ambitions of Dublin Bay South Fianna Fáil TD Jim O'Callaghan, in either a positive or a negative way.
Even more galling is the rising and steady fortunes of Fianna Fáil's Coalition partners. Leo Varadkar's Fine Gael scored just 21pc in the election. But its fortunes have gone up - and stayed up, with yesterday's poll putting it on 35pc. Even the Greens are going well on 6pc, just about where they were in the election, signalling Eamon Ryan cannot be doing everything wrong.
There may be a clue to the cause of these survey results to be found in another opinion poll, for the Sunday Independent.
That timely research by the survey organisation Kantar comes six months after the World Health Organisation declared this virus a pandemic, and just days short of the six-month mark since the pubs were locked on March 15.
This research shows how the nation has changed its take on the government handling of Covid-19. Back in mid-April, almost half of the people "strongly approved" of the government response to the emergency.
But that has fallen progressively since then and by late last week it was put at 14pc - just one in seven people roundly endorsing the Government's actions.
Kantar director Paul Moran points out that two out of three of us still deem Covid-19 a serious problem which will be with us for some time. Many people are rather downbeat about the resultant economic prospects with just one in five thinking there will be a swift recovery.
The big-picture impression from the Kantar research is people are getting restless in differing ways. We are no longer "all in this together", as the widespread national vibe had it when Mr Varadkar delivered his St Patrick's Day address to a locked-down, pub-less nation.
But the 'Churchill-dividend' stays with him and Fine Gael. It may be reinforced by their ministerial team having nine years' government experience and more established media structures.
Mr Martin's stint on the Taoiseach's bridge is a much tougher shift as national moods oscillate. Add some bad luck of 'events' since taking office on June 27 last, and you could be on your way to explaining why times are so black for the Soldiers of Destiny.
Well, not quite. You see this chronicle of Fianna Fáil travails foretold was written well in advance.
Remember Éamon Ó Cúiv, former Fianna Fáil deputy leader and grandson of party founder Éamon de Valera, speaking from his Gaeltacht fastness in south Connemara before the coalition deal was done with Fine Gael?
Well, he was back yesterday with a pithy bit of 'I told you so' on the Twitter machine.
He just might be strangely pleased his predictions are coming true - though surely surprised at the speed of calamity to befall his party. But he gave things a biblical twist by mistakenly referring to the surveyors as "Red Sea". He argued this party's fortunes could not easily be explained away - and some fundamental shriving was now urgently needed.
"Red Sea [sic] Poll. Looks like my prediction of there being two large parties but FF not being one of them, is coming to pass. The threat is existential. FF won't survive if we persist with the myth that the decline is simply due to external factors and not the party's direction," Mr Ó Cúiv wrote.
This brings us to Sinn Féin and the shadow over Micheál Martin's shoulder on a permanent basis. In the General Election, Sinn Féin got almost 25pc and made much of being "excluded" from coalition talks with the two established parties.
Since then, Mary Lou McDonald's party has been motoring well, though not gaining spectacularly. Yesterday, they were on 27pc, reminding everyone that with an aggressive election strategy next time they might become the biggest party in Dáil Éireann.
But the core of Mr Ó Cúiv's warning is that politics is rapidly heading towards being Fine Gael versus Sinn Féin, with his own Fianna Fáil becoming a much-diminished sidebar on the slippery slope of being consigned to history, like the old Irish Parliamentary Party. Hence his words that "the threat is existential".
Fianna Fáil's current predicament is pretty dire and they need to up their government game. Much hangs on presenting the new six-month strategy on living with Covid-19 this week.
Mr Martin needs to bring his A-game and address a fretful nation who need coherence on what is going on - and what precisely the Government intends to do.
The Taoiseach and his ministers also need to keep up the moral pressure on Boris Johnson over his disgraceful behaviour around Brexit.
All international pressure must be applied upon London in a most sustained way.
One of the few silver linings is that options are limited for Fianna Fáil in government - they just have to keep going - and hope for better political weather.
