No. I'd guess they both think this the best way to keep a Tory government. The next election is more than 2 years away, plenty of time for the party to regroup under a more credible leader (likely one of them, in their minds). The longer Johnson remains in place the harder it will be for them to win next time.
I don't think this is good news if you're hoping for a change of government. The electorate is basically right wing. I think many would have found it hard to vote for Johnson again, but a straight Labour v Conservative and it will be business as usual by Dec 24 IMO
