PHILADELPHIA — Tim Kaine has an impressive resume to be sure, but it is not quite as unique as advertised.

The junior senator from Virginia and Democratic vice presidential hopeful had said he was one of just 20 people to have served as a mayor and a governor as well as a senator. But it turns out that claim was somewhat incomplete.

It was built off a list of people who were mayors and governors before they arrived in the Senate, not instances in which the offices were held in different orders. Twenty-one people accomplished that, including Kaine.

The biography on Kaine’s official Senate website has already been updated to reflect that the total is now 30.

One of the members of that group, Francis Emroy Warren, served as governor of Wyoming for only one month while it was a state, having been the territorial governor before his election to the Senate.
