I need to figure out how a native would describe this situation? Let's suppose someone is packaging current or old ideas and practices in a way which makes them appear to be modern/innovative, particularly with the intention of pretending that they are "new" or keeping them alive or making them look more attractive to audiences who are unfamiliar with them or have some objection to them.
E.g. Scenario 1) Please imagine a situation in which someone (the boss of a company, a salesman) is promoting something as being all new, "but it isn’t really new" and at closer examination it seems to be the same as before just "rebranded", "repacked", "got a new name "or a fresh label. So they are selling an existing product just with another appearance! A customer who can grasp the identity of the prodoct and just was presented, tells his wife softly: It is the same old wine is new bottle!
Scenario 2) In a country the president changes; ordinary people believe all the elections propaganda and exagerated media advertisements about the upcoming president! They believe that by changing the president the current situation would be changed into a better one! Unaware of the fact that all the politicians of one regieme are working under the same flag, observe same regualtuons and fight for the same target in that country! A wise person who is a witness of all the happenings mumbles: It is the same old wine is new bottle!
I need to know if the bold sayinga work properly and idiomatically in these cases of mine?
