"I love a 50-50 tie," Senator John Breaux of Louisiana told me recently. "This is the kind of thing you dream about being involved in. It's a mandate for getting things done." And, boy, does he want to get things done. Breaux has a reputation in the Senate as a consummate deal maker, a people person, a backslapper. He's a Democrat who more often than not agrees with Republicans on signature issues like Social Security and Medicare, so his penchant for compromising and deal making has many Democrats worried. According to the prevailing wisdom, Breaux looks perfectly poised to serve as George W. Bush's go-to man in the Senate. But there's something funny about Breaux's deals: They never quite seem to get made.
