Matt Hancock also sees a 20-point rise in his approval rating to take third place as the Covid-19 crisis reshapes British politics.
Seventy-seven per cent of those polled back the lockdown; 90 per cent think the Prime Minister and his team are handling the crisis well.
The overall numbers are down slightly after the allegations against the Home Secretary and the Government’s defeat over Heathrow.
They don’t believe that the Government’s moratorium on it is justified by the evidence about safety.
These results are moderately encouraging for Boris Johnson and his team as they head towards this autumn’s COP26 summit in Glasgow.
Our sense is that Conservative MPs will be very roughly where our panel is – although we have to admit that we’ve no evidence for that.
They reject that claim that there is one by about two-thirds to one third. Our other survey findings on the same theme will also be published this week.
The month-on-month stability in our rankings highlights against just how much an overall majority has calmed British politics.
Our survey is a snapshot, five years before the event, but this is the starting benchmark: can the Government possibly keep confidence levels this high?
The Chief Secretary to the Treasury wins decisively with over half the vote. Johnny Mercer was the runner up, with more than a quarter.
And by ranking Rayner second, they appear to agree that “Rebecca Long Bailey isn’t even the best Labour leader in her own flat”.
They support raising the threshold by two to one – a useful reminder that the Prime Minister cannot ignore his Party’s base.
Cummings is clearly a winner – and Party members want to keep hold of him now that there is a Tory government in place with a big majority.
The Prime Minister heads a Cabinet whose stock has risen markedly in the wake of this month’s decisive election victory.
The Spartans played a major role in sinking May’s Brexit deal and floating Johnson’s. Baker has thus been a force to be reckoned with.
Almost nine in ten of our panel members say that he has much to do before he can be counted the equal of Margaret Thatcher.
He is one of the few elements of continuity in what has been a turbulent year at the Government’s top table.
Whilst individual ministers rise and fall, overall the Government goes to the polls with a lot of goodwill from grassroots Conservatives.
P.S: “For frantic boast and foolish word – / Thy mercy on Thy People, Lord!”
These findings compare to a 64 per cent total in June, when Theresa May was still Prime Minister, with a leadership election looming.
Not a good month for the Foreign Secretary, who slips from third place to eighth. But this is probably just due to the rising popularity of others.
It is perhaps not surprising that a majority of activists believe, however narrowly, that it makes sense to work with another party that wants to leave the EU.
You don’t really get closer to unanimous than this in our surveys of Conservative Party members.
Brexiteers retain their stranglehold on the top of the chart, but there is a general downward drift. Is it a foretaste of what might happen if we fail to leave the EU next month?
It is possible that, in the wake of last week’s Supreme Court ruling on prorogation, they are a kind of advance indicator: seven out of ten respondents want change.
The Benn Act and the Supreme Court verdict have clearly had a very substantial impact on expectations.
The data for this was collected before the Government’s string of Commons defeats – next month’s may look rather different.
And some two in five would back it. When asked about a time limit on the Northern Ireland backstop rather than abolition, support falls to roughly a third.
And eight in ten back the prorogation decision. Party members are fully behind their leader.
They aren’t just optimistic about Johnson’s electoral prospects, they have faith that he will fulfil his ‘do or die’ pledge.
