If the Senate splits 50-50, you know exactly what Chafee will do.
Fortunately, in just that scenario, Dick Chaney casts the deciding vote!
But I understand what you mean give or take one vote.
You're right. We can't rule that out. I believe Chaffee (in the past) has indicated he might do a party switch.
I think it sucks. I also wish Steve Laffey had won the primary over Chaffee.
As it stands, the GOP will no longer have to worry about Chaffee soon. Most polls have him losing to the Democrat, Sheldon Whitehouse.
