Should a Pre-nup be a legal requirement before marriage?

I went to a Christmas party and talked to a guy (wealthy lawyer) who plans to run for office in my state. He was a little drunk, maybe I was too. Having said it, he thinks most men get married without understanding the divorce laws in the state. His campaign message is that he will make a pre-nup mandatory in our state.
I told him that it just might get voter attention.
The majority of voters in my state are males. The women who support loser men will love it too. Divorce lawyers will rally to oppose it.
Still, It sounds like a winner to me.
What do you think?
