In a system where a single person gets full executive authority,

Well, that’s the problem, isn’t it. No single person should have that much authority. But, regardless, does this debate platform really tell us all that much about how a person is likely to perform as chief executive? I’m not so sure. I think a person can do relatively well in a debate performance and still end up being a poor president.

I can’t vote for policies.

But you can vote for a representative (two, actually) who can vote for policies. That’s where our focus should be, I think. I’m not really sure why we need a president, to be honest. A single individual with that much power, who isn’t even elected by popular vote, seems undemocratic to me.
