@Stefan, as @Mel Hopkins pointed out above, it's not about blaming Democrats or other groups for failures.
The fact of the matter is that Democrats could have codified these things into law when they were in majority over a decade ago. Unfortunately, they are not aggressive enough when it comes to pushing legislation.
OTOH, the obstructionists (Republicans) have been saying all along that they are going to overturn everything that benefits minorities. When they do have power...they wield it from appointing SCOTUS nominees to enacting laws.
I have zero issue with calling balls and strikes as I see them regardless of political party. From where I sit, both parties are total agreement when it comes to one thing...maintaining white supremacy.
