In 2008, after John McCain’s surprise announcement that he had selected Sarah Palin as his running mate, The Washington Post reported an intriguing coincidence: Leading up to the announcement, Palin’s Wikipedia page had seen more than 65 edits over the course of the day.

Can Wikipedia edits reveal something similar in this election? Hillary Clinton is expected to announce her VP pick in the coming days—or hours. Which potential candidates have seen the most edits to their Wikipedia pages this week?

Let’s review.

The page of Ohio Senator Sherrod Brown has seen several changes over the past week. Elizabeth Warren, the senator from Massachusetts, saw few edits this week after an elevated number earlier this month, when she was touring with Clinton.

U.S. Secretary of Housing and Urban Development Julian Castro’s page received about three edits per day this week, though most of the edits concerned his alleged violation of the Hatch Act.

Tom Vilsack, the U.S. Secretary of Agriculture and one of two candidates on Clinton’s reported shortlist, saw about 30 edits to his page this week. Most of them were just to clean up information already on his page, and they came from registered Wikipedia users.
