When is the last time that happened?
Excuse me. “When WAS the last time that happened?”
When is the last time that happened?
When it happens, nobody notices.
We just complain as usual about the way things are.
It's when it doesn't happen that people notice, and remember.
Also, there's a threshold involved: all politicians have their own pet constituencies and interest groups that they try to benefit, but when they really leave some group in the lurch, people feel it and resent it.
