I actually did know that, but it doesn't invalidate my point whatsoever.
If Democrats were truly supportive of working class people they wouldn't be voting to remove their collective bargaining rights via an act of Congress. Think about that for a second -- they would rather vote to send those workers to jail than allow them to exercise a core right of workers everywhere.
Doesn't matter that Biden stepped in months later, Biden is the president and I'm talking about the general party in Congress, e.g. Democrats en masse.
