Disappointed Democrats were holding out hope that a recount would unveil some massive fraud on the part of Donald Trump/Russian hackers etc.
These people were so passionate that Green Party nominee Jill Stein was able to use them to fuel her statewide efforts. Stein, though, has been generally unsuccessful.
Furthermore, those areas that have conducted recounts found little or no change.
Today Stein announced she is filing suit in federal court to get Pennsylvania (as well as Michigan and Wisconsin) to hold statewide recounts. This is likely her a last-ditch effort on her part.
