Next stop, mandatory reading of Going Rogue? Talking Points Memo reports that the Republican National Committee is considering a purity test for political candidates. The “Proposed RNC Resolution on Reagan’s Unity Principle for Support of Candidates” lays out 10 issues and, if adopted, would cut off party support and money from candidates who disagree with three or more of them. Issues include opposition to cap-and-trade legislation, a rejection of amnesty for illegal immigrants, and support for a troop surge in Afghanistan. The RNC will vote on the resolution in January.
