JEFFERSON CITY, Mo. (AP) -- Supporters of Republican presidential candidates Mitt Romney and Ron Paul have forged an alliance in some of Missouri's local caucuses.
Rick Santorum easily won Missouri's non-binding primary last month. But he was shut out from receiving delegates at some of the local caucuses that occurred over the weekend after Romney and Paul supporters combined to advance their own slate of delegates.
Missouri's local caucuses are being used to select 2,123 delegates to advance to regional Republican conventions April 21 and the state convention June 2.
It's at those later meetings that delegates actually will be bound to support particular presidential candidates. That means Santorum still could emerge with most of Missouri's delegates. But that could be made more difficult if supporters of Romney and Paul stick to their alliance.
