It seems you are clearly understanding? You are likely just confused because you do not understand that the overarching objectives of the "uni-party" or "deep state" system hold fast, it's just that each political sporty ball team has to play things different and tell different lies in different ways to different cohorts in order to keep the system operating. So, e.g., Biden says we need 300M more immigrants and his team fans cheer because they support it, wile deporting more people than Trump; while Trump tells his team fans that he will deport people and does this whole theatrical ICE stuff to give the impression of deporting people to drive down costs and retain their support, but in fact barely moves the needle on deportations and committing to 600,000 more Chinese students and wanting to "staple citizenships to diplomas" for millions of Indians, etc.

You have to understand that there is the theater of the political sport ball arena where the different sides are set against each other like WWE/Football, etc. but in the background it's just actually all more or less rigged and the truth is written in policy and strategic papers that are implemented over 20+ years, across presidents and their wrangling and herding of their constituents in this charade called "democracy".
