Rep. Brad Ellsworth's (D-Ind.) Senate campaign has raised $625,000 in the last six weeks, according to a release. The Ellsworth camp noted that 80 percent of the contributions were from in-state donors. It now boasts more than $1 million cash on hand.

Ellsworth will also benefit from the $1 million that retiring Sen. Evan Bayh (D-Ind.) transferred to the Indiana Democratic Party in March. Bayh spent close to $2.3 million on his 2004 reelection.

Former Sen. Dan Coats (R-Ind.), the leading contender for the GOP nod, has not yet released his first quarter fundraising numbers.
