The Wisconsin State Journal reports that Sen. Russ Feingold's campaign has registered russfeingold08.com. Normally, this wouldn't raise any eyebrows except that Feingold is not up for re-election for his Senate seat until 2010 fueling speculation he is exploring a run for president.

"'We saw so many sites being snapped up out there that we reserved a few sites,' says George Aldrich, Feingold's past campaign manager. He notes that many sites, such as www.russforpresident.com, seeking to draft Feingold, are already taken and some already have content. Others are parked by supporters in case Feingold decides to run."

A whois search shows the campaign has registered the .net and .org variants of the domain as well.
