If you want an early hint about who presumptive Republican presidential nominee Mitt Romney will pick as his running mate, keep an eye on Wikipedia.
That's the advice of the website TechPresident, which notes that Sarah Palin's Wikipedia entry was updated at least 68 times the day before John McCain announced her as his vice-presidential selection, and 54 more changes in the five days before that.
So where's the current action on Wikipedia? TechPresident reports that Wisconsin Rep. Paul Ryan, Florida Sen. Marco Rubio and Louisiana Gov. Bobby Jindal have had multiple edits on their Wikipedia pages in the last week.
