This revelation Ambinder caught hold of from an "RNC rules maven" is disturbing, to say the least:
Republican rules for the first time give the members of the Republican National Committee, by a 2/3 vote, the option of adopting a mandatory 2012 state primary election calendar.
States whose legislatures, which may be controlled by Democrats, refuse to schedule a primary that complies with RNC rules face a draconian choice.
Either their party gives up its presidential primary and instead holds (and pays for) a presidential preference caucus -- or the state suffers a loss of 1/2 of its delegates to the 2012 Convention.
Many party leaders, who, for ideological or personal reasons, prefer a low-participation caucus rather than a higher-participation primary, see this Rule as a great opportunity to transform the party.
