For some congressional candidates preparing early for the 2010 elections, the best seed money is their own personal funds.

Suzan DelBene, a Democrat from Washington state, and Kansas Republicans Dick Kelsey and Tim Barker all reported six-figure personal loans to their campaigns in this year’s first quarter, according to just-filed campaign finance documents. There is no limit on how much personal money a candidate can put into his or her own campaign.

DelBene, a technology executive who is running against Republican Rep. Dave Reichert in the state’s 8th District near Seattle, contributed or loaned her campaign $209,000 — about two-thirds of her total first-quarter receipts of $315,000. Her personal funding enabled DelBene to post more overall receipts than Reichert, who raised $195,000 during the reporting period.
