"Why is everyone overlooking one of Wellstone's sons as a replacement?"

Because you must be 30 years old, and neither of them is!

I've seen his son David mentioned as a possible replacement in one or two articles.

Dude what is his age? I've not been able to find it listed anywhere.... But Wellstone was born July, 1944, married in 1963 and had three children with David being the oldest. Depending upon how long after he was married that David was born it's very possible for him to be in his mid 30s or more.
