Mulligan's view of the prime minister has darkened as the campaign has progressed and she now regards May as both uncaring and untrustworthy.
Now, the brazen confidence is less visible, thanks to Labour's popular manifesto and its leader Jeremy Corbyn - who was supposed to be unfit for politics in the age of television - growing in stature and popularity by the hour.
Yet, as voting day looms, those fears are looking less and less likely. "A small majority would likely give more weight to the Brexiters in the Conservative Party, heightening the probability of a clash".
Sander's praise for Corbyn comes after a recent YouGov poll shows Labour trailing the Conservatives by just 3 points. "There are other people in the party, not just him", he said. And secondly, could the polls just be wrong?
Mrs May was also confronted by two voters who had been called to work capability assessments over mental health conditions, one of whom said she had been waiting nearly two years for NHS counselling.
By contrast, it was on domestic spending that Corbyn was at his most comfortable. That marked a break from the Conservative pledge under former Prime Minister David Cameron in a 2015 election campaign not to raise income tax, national insurance contributions or VAT.
Ukip member Abigail Eatock won loud applause as she told the PM: "You said you wouldn't call an election and you did".
That said, the Conservatives are behaving as though they still expect to win a decent number of extra seats - and are certainly not behaving as though they think we are heading to a hung parliament.
But things weren't so simple.
Afterwards, Labour leader Jeremy Corbyn faced the same audience and his own tough questions over his party's manifesto of spending promises - which one audience member called a "letter to Santa Claus" - and his record on defence.
The overall pattern was clear: Theresa May was hammering away with visits which imply she thought the Tories were going to advance a long way.
The Voter-May dynamic proved promisingly positive during the first period the prime minister's time in office, Britons believe that she had struck a balance between committing to implementing Brexit -which the British voted yes for- and protecting United Kingdom economic, political and social interests by maintaining a close relationship with European neighbors on the other hand.
I could have stayed on and kept doing that job.
For Mr Corbyn, the questioning started more gently, but he became irritable when repeatedly asked about whether he would be prepared to use nuclear weapons. "I think the idea of anyone anywhere in the world using a nuclear weapon is utterly appalling".
The BBC has confirmed that for audience recruitment it uses open-ended online forms, which sources told the Telegraph is the riskiest kind for avoiding biased and one-sided crowds. You have to bring about a peace process by talking to people that you don't agree with.
But Mr Corbyn, despite more latent comfort in his own skin, also faced pressure.
In her session, May was asked why she was not able to provide details of the maximum amount of money people would have to spend on social care, which was only promised after days of backlash against the policy.
Mrs May was challenged over the changes during a special BBC Question Time programme, but she insisted the reforms were "fair".
His plans set out to rebalance years of Conservative rule, which has seen net investment in the public sector declining and average wages plummeting in real terms.
The Labour Party on the other hand as come up with a populist manifesto promising to nationalise rail and mail, to remove tuition fees for students, put more police on the streets and allocate more funds for the National Health Service which many say is slowly crumbling, and to build more housing.
