The Republican National Committee is meeting in Tampa. According to this news story, on August 4 the Committee defeated a proposal to increase punishment on states that hold presidential caucuses or primaries earlier than March. Four particular states have special permission to go earlier, and they were pushing for the additional sanctions.
The problem with the major party rules that gives special treatment to four particular states (New Hampshire, Iowa, Nevada and South Carolina) is that those rules lack legitimacy. There is no philosophical foundation for the idea that voters in four particular states deserve permament favoritism. Thanks to Frontloading HQ for the link.
