With news that Republican U.S. Senate candidate from Illinois Jack Ryan may withdraw from the race over a sex scandal, there is already talk of replacing him. A.P. reports: “The GOP cannot force Ryan off the ballot. But if he drops out before Aug. 27, the party can put up a new candidate.” I have not looked at Illinois law, but readers may recall a controversy over interpretation of a New Jersey law for replacing Senate candidates that came into play when Robert Torrecelli withdrew from the race late in the game.
