Deep state (is generally agreed to be) non-elected officials who have the ability to sway govt functions. It’s more about making things not happen.

The “resist” movement from the first admin could be seen as an example of deep state. If an elected person wants to do something that they have the power to do but the lower levels of govt disagree (ie it isn’t in someone else’s best interest) suddenly there will be things to stop it from happening or make it so slow, painful and costly that the elected would rather do something else instead.

Errors in paperwork, extra “random” inspections, key people in the process calling sick, insisting on following all procedure step by step no matter what.
