He specifically mentioned a Senator. I've heard this discussed by a conservative panel. Roosevelt stacked the court with former political people and it wasn't good for the country. I don't mind non-judicial, but I'm not sure I want a former politician. It depends on who it is, I guess. I'm not anti-politician, but I want decisions based on the merits according to the constitution. Whoever can do that is the person I want.
So, why not you? Or me? We are reasonable, we are somewhat articulate, we can read the constitution. It's really a pretty simple document, which the legal community managed to twist to fit their agenda. There are many examples how the supremes 'interpreted' the constitution, set federal laws, which clearly were supposed to be left to the individual states.
Orrin Hatch has been mentioned in the past, but he has shown himself like all the other senators -- worthless.
