A special straw poll will be taken to gauge support for individual Republican Gubernatorial candidates. Currently four statewide Republican governor candidates are in the race, and Marshall County Republicans will have the opportunity to show their allegiance. The results of this straw poll will be available after the caucus.
The caucuses will begin creating the platform planks for the group, and elect members to the Marshall County Republican Committee, and will elect delegates and alternate delegates to the Marshall County Republican County Convention to be held on March 6.
