Senate Minority Leader ______

It’s hard to choose the single most disheartening defeat from yesterday, but seeing Tom Daschle lose in South Dakota has to be right up there. Looking ahead, however, we need a Dem to fill his role as the party leader in the Senate. It may quickly get competitive, but a frontrunner already seems obvious.

Senate Minority Whip Harry Reid (D-Nev.), who cruised to re-election yesterday, will announce his intentions today and get a head start on potential challengers. Indeed, Reid’s staff was making similar announcements last night.

Reid wants the job badly and a lot of lawmakers owe him some favors, which certainly makes him the odds-on favorite. But Reid as Minority Leader is not without risks.

Pros — Reid is exceedingly smart, tough, and has a reputation for unwavering honesty. He isn’t an in-your-face type or an inspiring orator, but he’s downright brilliant behind the scenes. Remember when Dems convinced Jim Jeffords (I-Vt.) to leave the Republicans? Reid made it happen. Moreover, Reid is also known as a centrist, so he’ll hardly be an alienating figure or GOP punching bag.

Cons — He’s from a relatively Republican state, so Reid may have to put his own interests above the party caucus’ from time to time. More importantly, Reid is — I hope you’re sitting down — opposed to abortion rights, which clearly puts him at odds with the overwhelming majority of congressional Dems on a high-profile issue.

Reid’s efforts this afternoon will give him a critical head start in the race for the job, but I’d be surprised if he didn’t face a rival or two. Among the names floating around: Chris Dodd (Conn.), Dick Durbin (Ill.), and Hillary Clinton (N.Y.). All three steer clear of the “cons” listed above, but none have been building up a favor reservoir the way Reid has.
