Cabinets Initial Distribution


In every game I have played the distribution of leanings amongst the members of the PMs cabinets are identical.
Conservative II
Capitalist II
Environmentalist II
Trade Unionist II
State Employees I
Farmers I
Commuters I
Patriots I
Socialists I
Religious I

Is this a function of the Innate Liberal, Innate Socialism, Political Apathy & Difficulty sliders?
If not, then what determines the leanings of the cabinet?
