(CNN) -- Mitt Romney is expected to announce his vice presidential running mate any day, and the certain GOP nominee's campaign is asking supporters to download "Mitt's VP" app, which has the primary purpose of sending a push notification with the name of Romney's choice to users before the official announcement to the press. For the impatient, the Tech President blog has brought up an interesting possible early indicator: activity on potential picks' Wikipedia pages. In the past, Wikipedia activity has spiked for vice presidential picks the day before an official announcement was made. In 2008, hours before Republican candidate John McCain announced his vice presidential choice, Sarah Palin's Wikipedia page was getting a heavy edit. According to The Washington Post, the then-Alaska governor's page was changed 68 times the day before the announcement. In the 24 hours leading up to Obama's running mate announcement, Joe Biden's page was edited 40 times.

The Tech President looked at Wikipedia activity for these and other potential choices on Monday, and though it found some interesting numbers, no one page has yet seen the one-day levels of activity experienced by Palin's and @placeholder's in '08.
