Torricelli, Murkowski, Burris & Ensign: That’s not the newest lobbying law firm on K Street, but rather a roster of senators whose extraordinary political careers point toward the four tough paths for Republicans intent on keeping Roy Moore out of the Senate.

The lateness of the electoral hour, combined with Alabama’s deeply red nature and solid support from the state’s GOP base, continue to afford the 70-year-old, twice-removed chief justice of the state Supreme Court big advantages if he persists in his campaign — notwithstanding allegations that while he was a prosecutor in his 30s he sexually assaulted two teenage girls and pursued romantic relationships with others.

Moore is giving every indication he’s pressing ahead to the special election in four weeks. And that’s as a growing number of would-be congressional colleagues have urged him to get out of the race or face the possibility that, should he win, he’ll be ostracized at best or, at worst, prevented from taking his seat or quickly expelled.
