They've certainly not done as much as they could have, but them's the Democrats, and the Democrats aren't "the left".
They are on the left side of the aisle.
So let's not try to escape responsibility with the No-True-Lefty fallacy.
Also, they have been introducing police reform.
Introducing very very little.
Only a few states are curbing qualified liability.
And none are raising standards for hiring, training,
monitoring, & sanctioning illegal behavior of cops.
Based on the things you listed. Which party handles homelessness, police reform, social safety nets and crime better?
Both handle it badly.
Let's not take refuge in....
"We're bad, but they're worse."
Right. But that doesn't mean that one party isn't significantly better at doing generally "good" things than the other.
I'm not a big fan of "both sidsing" when one party is just a generally ineffectual party of liberals who are nonetheless at least making token efforts to enact legislative changes to improve people's lives, and the other is doing everything it can to make everything worse.
But you are a big fan of using the "but they're worse" apologetics.
So I'm disgusted by sanctimonious Democrats feigning sainthood
when demonizing Republicans as the sole problem.
