Kinga would be likeliest because she's a 2nd termer, she represents Doug's home riding, and she's long rumoured to be his extra-marital paramour. So in case he's up to some "Lurleen Wallace" thinking...It would not surprise me if in a leadership contest Doug Ford asked Kyla, Kayla, Krista or Michael to run for the leadership.
One thing about the Fords is their brand. They think of themselves like the Kennedys where there always has to be a Ford on the ballot.
