Josh Gerstein has written two election law articles for the NY Sun: Ad Against Lieberman Divides ACLU, which is a must-read for anyone interested in the line between election-related speech and “genuine” issue advocacy, and Group Shells Out $1M To Boost Santorum’s Popularity with Women. A major donor behind the donations has renounced his American citizenship, and a reader writes to ask whether this donation violates McCain-Feingold’s prohibition on foreign national contributions even to 527s. I have not looked into this issue, but would like to hear from others on it.
