Welllll... the problem is that the ISPs will build systems to collect the data NOW. By the time a new administration comes in, they will have enough data to profile you for the next 10 years, if not for life.
And if you think they will turn off these capabilities in the future... yeah... that's not gonna happen. They will say that they are not tracking that information, but they will. And they will just use it in sneakier ways.
I know this because I was a sysadmin for email systems for the Federal Government.
Client: "Can you read my email?"
Me: "No." (lying)
