Since the campaign began a year ago, the former Democratic National Committee chairman has raised $7.4 million. He has consistently outpaced his chief rival, former governor and senator George Allen, in a race that is expected to be one of the most expensive in the country.

Kaine received donations from more than 19,000 individuals since last year; 6,000 new donors made contributions of $200 or less in the first quarter, bringing the total number of low-dollar donors to more than 14,000, according to the campaign.

Kaine automatically became the Democratic nominee for U.S. Senate when no others submitted signatures to have themselves place on the ballot by last week’s deadline.

The four Republicans who are running in the U.S. Senate primary in June have not released their fundraising totals for the quarter. They are: Allen, tea party activist Jamie Radtke, Del. Bob Marshall (Prince William) and Bishop Earl Jackson.

Allen has raised $4.5 million. Radtke and Jackson have each raised less than $1 million. Marshall recently jumped into the race and has not reported any fundraising numbers yet.
