The Supreme Court is a joke
Judges should never be picked by a political party
Mitch McConnell broke the system by Republican majority
We now have 5 Republicans in the Supreme Court
Mitch Connell already said if Republicans get a majority in either house he will block any SC candidates from Joe Biden
just like he did with President Obama
With life time appointments it will be a decade before the court is balanced again 🤬🤬🤬🤬
