Former Virginia Gov. Tim Kaine’s Senate campaign had a monster first quarter, raking in $2.2 million and ending March with $4.4 million in the bank.

Kaine, the former chairman of the Democratic National Committee, is unchallenged in the June 12 primary and likely to face George Allen, a former governor and Senator, in a general election race anticipated to be among the closest in the country and instrumental to both parties’ quest for the Senate majority.

The Kaine campaign highlighted in a release today that it has raised a total of $7.4 million in the past year from 19,000 individual donors, including more than 14,000 who have given $200 or less.

Allen has not yet announced his first-quarter fundraising. Reports for the Jan. 1 through March 31 fundraising quarter are due April 15 at midnight.
