( 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 . While there 's no official list of people being considered by the Romney campaign , a few names have been bouncing around , including Rob Portman , Marco Rubio , Tim Pawlenty and Paul Ryan . 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 Biden 's in '08 . On Monday , Wisconsin Rep. Paul Ryan had the most changes with 10 , but on Tuesday , Ohio Sen . Rob Portman took the lead with 16 changes made by a Wikipedia user called River8009 . The anonymous user deleted a section on controversies , a paragraph about NAFTA and various criticisms of Portman . When the seemingly biased edits were noticed , other Wikipedia users organized on Reddit message boards and acted to revert the changes and lock the page to prevent more tweaks . River8009 was flagged by Wikipedia for having a `` possible conflict of interest . '' Marco Rubio 's Wikipedia page was also quite active on Tuesday , and the comments on the changes are an interesting peek at the Florida senator 's supporters and detractors . The primary argument was over whether to include a quote calling Rubio the `` crown prince of the tea party movement , '' with some tea party members disputing the title . Recent Wikipedia edits could be the work of hopeful candidates wanting to look better to the Romney campaign as it deliberates ( though a presidential candidate likely uses more than Wikipedia to vet vice presidential running mates ) . It is also possible the Romney campaign has learned from the past coverage of Wikipedia edits and will only make changes gradually leading up to an official announcement .
In past elections , favorable edits have served as signal for potential presidential picks . Edits tend to appear right before a candidate is chosen as running mate . 1 . Rob Portman 's website had a spike in favorable edits on Twitter .
