Four potential candidates for governor will appear, together, at a northwest Iowa event this morning.

Two of the candidates have already filed papers creating "exploratory committees." It means Bob Vander Plaats and Christopher Rants can start raising money for a campaign. Both men are from Sioux City.

The other two Republicans who will appear this morning at the Sac County Republican event in Sac City are state legislators. Representative Rod Roberts is from nearby Carroll. Senator Jerry Behn is from Boone. Both have said they’re thinking of running for governor.

This morning’s event starts at 8:30. Tickets are $10 each. The Sac County GOP has offered to share the proceeds from the event with a candidate. The requirement: the candidate must use this morning’s event to "formally announce" they’re running for governor.
