> He was impeached years ago…
"was impeached" means different things in context.
Sometimes it means "articles of impeachment were brought against an official". (1) i.e. that the process starts.
Sometimes it means a later stage in the process, such as those article not being voted down, and a trial proceeding.
In the strictest sense, it means that the process completes - "the official is found guilty, removed from office, and may never hold office again".
Parent comment seems to be using the strictest sense, due to "and would have never managed to get a second chance". You're not helping by using a confusing different meaning.
