Here's some rationale on why it's worth using HTTPS for everything, even the less sensitive things:

https://https.cio.gov/everything/

A lot of people focus on targeted surveillance of people visiting individual sites, but there are so many other threats and issues out there. Bulk modification of unencrypted traffic is a particularly nasty one, and has been seen in the wild, at scale, multiple times.

A US .gov page recommending the use of HTTPS everywhere, in a thread complaining that another US .gov site recommends using HTTP over HTTPS. I find this hilariously ironic!

The world is a complicated place, and the US government is a highly decentralized organization. (And in the case of the executive and legislative branches, decentralized very much by design.)
