Gov. Bob McDonnell’s political action committee, Opportunity Virginia, raised $1.53 million in the three-month period that ended June 30, according to the governor’s office.

McDonnell has a hefty $2.96 million in the bank heading into the fall as he and his Republican allies look to take control of the state Senate, where Democrats hold a fragile 22 to 18 majority.

Republicans are looking for allies to pass school choice bills, immigration law enforcement, pension system changes and other priorities that have died in past years at the hands of a Democratic-led Senate.

“This strong continued financial support is reflective of Governor McDonnell’s strong record of results: expanding jobs and opportunity; reducing the size of government; and making historic investments in transportation and higher education,’’ said Phil Cox, McDonnell’s top political adviser. “The strong financial position of the Governor’s PAC will allow him to support candidates this fall for the Virginia House of Delegates and State Senate who support his positive jobs and opportunity agenda.”

By comparison, at the same point in his administration, then Gov. Tim Kaine’s political action committee, Moving Virginia Forward, reported raising $827,000 and had $1.3 million cash on hand at the end of the second quarter in 2007.

Kaine helped Democrats take control of the state Senate in 2007.

If Republicans are successful, it would be the second time since Reconstruction that the party held the governor’s mansion, House and Senate at the same time in Virginia.

Figures from the fundraising period, which are due Friday, are not yet available for both parties. Officials with the Senate Republican caucus declined to release their numbers.

Senate Majority Leader Richard Saslaw (D-Fairfax) said recently that Senate Democrats have about $1 million in the bank to give to candidates and expect to raise an additional $1.5 million before the November elections.
