The Christian Science Monitor notes Sen. McCain’s views on the DISCLOSE Act in this recent article.

The most likely Republican prospect, Sen. John McCain (R) of Arizona, led a long legislative battle together with Sen. Russ Feingold (D) of Minnesota to pass historic campaign finance legislation in 2002 that limited how much corporations and unions can spend to influence elections. Those limits were scrapped by a controversial US Supreme Court decision in Citizens United vs. Federal Election Commission in January.

But McCain says he will be no part of advancing a bill that requires more disclosure of corporations than it does of labor unions. “It’s no surprise that Democrats craft a bill that favors their supporters,” he said, after the House vote.
