Rep. Jack Kingston hasn't said he's running for the U.S. Senate, but he's raising money as if he plans to ask Georgia voters for a promotion.

The Savannah Republican raised $842,000 in the first three months of 2013, according to campaign filings with the Federal Election Commission. That's 10 times what Kingston raised in the first three months of that last election cycle. At the end of March, Kingston had $1.75 million in his accounts.

Kingston is expected to announce soon whether he'll run next year for the Senate seat opened by Saxby's Chambliss's retirement. Kingston can use his House campaign money for a Senate bid.

Two other Republican congressmen, Paul Broun and Phil Gingrey, have said they'll run. Their campaign finance reports aren't publicly available yet.
