The anti-abortion group Wisconsin Right to Life (search) is airing a TV spot and radio ads about blocked judicial nominees aimed at Wisconsin Democratic Sens. Russ Feingold (search) and Herbert Kohl (search).

But come this weekend, the ad campaign will be illegal because of whom it's targeting.

Under the provisions of the McCain-Feingold (search) campaign finance law, special interest groups are prohibited from running corporate-funded radio and TV ads that mention a candidate's name within 30 days of a primary or 60 days of a general election. Feingold is on the ballot Sept. 14.

WRL insists its ad has nothing to do with electioneering and argues that citizens need to know whom to lobby if they oppose the fact that the Wisconsin senators are blocking confirmation votes on many of President Bush's judicial nominations. The nominees are considered by many Democrats to be too anti-abortion to sit on the bench.

But Feingold's campaign manager, George Aldrich, said the campaign is a "gimmick designed to score political points during an election by an organization that has endorsed all three of our potential Republican opponents."
