Former Pennsylvania Sen. Rick Santorum has won the Alabama Republican primary and is projected to win Mississippi. Will he make it a triple by cleaning up in Hawaii, too?

Santorum’s daughter, Liz, is here stumping for her dad. Speaking to supporters on national cable broadcasts he jokingly thanked her for her “sacrifice” in coming to the islands.

Mitt Romney’s son, Matt, and Ron Paul’s son, Ronnie, were also in the state drumming up support for their fathers.

Our caucuses start at 6 p.m. and end at 8 p.m. Results were expected shortly after the caucuses wind up.

Stick with Civil Beat’s live blog; we’ll be covering the caucuses statewide for the rest of the evening.
