The Senate has the exact same problem that the electoral college does.
For the SCOTUS, we do need a "highest court" but I'm certainly open to things like ethics requirements that are actually enforced. Don't know how I feel about lifetime appointments. Pros and cons there.
Who needs those pesky checks and balances? They just slow things down. I want my candidate to do what I want, without interference. I’m sure Bernie will be the next President and we can build trains just like China!
