From MOGOP.org:
The Missouri Republican Party recently voted to move to our caucus system for the purpose of binding Missouri’s delegates to the national convention. This change was prompted by new rules from the Republican National Committee & Democratic National Committee requiring states to move their binding nominating contests to March 2012 or later. Failure to comply with these rules would have resulted in the loss of half of Missouri’s delegates at the national convention. Any registered voter who declares that they are a Republican can participate in the caucus in the county in which they are registered.
