The Indiana Republican Party will undergo incredible change in the next few weeks as several of its top officials — including Chairman Eric Holcomb — leave the organization.

Holcomb abruptly announced his intent to depart the state GOP last week, along with several of his top lieutenants. A day later, Sen. Dan Coats, R-Ind., announced that Holcomb would become his new state chief of staff. Read more about the turnover in Roll Call’s weekly Shop Talk column.

Gov. Mike Pence, a Republican, will likely pick on Holcomb’s successor and state party members will approve that selection by vote. Those in the running include:

• Former Coats campaign manager Anne Hathaway
• Former state party Executive Director Jennifer Hallowell
• Attorney Robert T. Grand
• Pence campaign manager Kyle Robertson
