Kagan has sided with conservatives way too many times with the “look, their conclusion is poorly reasoned and unconstitutional, but you can technically get to the conclusion constitutionally from a liberal perspective if…” and then she sides with the conservatives.
Poking around in legal details can be fun, but she can be a professor while we get someone taking action on the court instead of siding with employer-imposed religious mandates over employee bodily autonomy (hobby lobby), supporting the “Muslim ban”(trump via Hawaii), and crippling contract law so that class action lawsuits can’t be brought against corporations over faulty or illegal contracts. (American Express versus Italian colors).
Kagan is not helping people, get someone on there who wants to help people.
