The Post reports that Gov. Kaine’s PAC is receiving large donations.

Since he took office in 2006, Kaine has raised about $6.5 million for his political action committee, Moving Virginia Forward. Of that money, nearly half of it came from about 75 people or corporations that have given at least $20,000 each.

One man, billionaire Randal J. Kirk, accounts for nearly one-tenth of the money Kaine has raised since 2006. Kirk has given the PAC $650,000, including a $100,000 check last month.

“It’s a good societal investment, and it is not a large amount for me, so I invest it in a place that can be good for society,” said Kirk, an investment and pharmaceutical mogul in Radford, Va.

Virginia is one of five states with no limit on how much an individual or a corporation can contribute to a candidate or state political committee, according to the National Conference of State Legislators.

In Maryland, which has some of the nation’s toughest restrictions, a candidate cannot accept more than $4,000 over four years from an individual.
