There has already begun to survey of the new Cabinet

A new cabinet was launched. The new cabinet members have to turn around their hearts, and have their national affairs committed.
However, each media have conducted a survey of the approval rating of the Cabinet all at the same time, but I find it difficult to understand.
Because, on the previous day, the new minister's is just decided.
If I were interviewed at such a stage, how would I answer.
I am fortunate that I was not elected.
