Senate Republicans raised $365,115 in the three-month period that ended June 30, according to the caucus.
The caucus has nearly $1.1 million in the bank heading into the fall as Republicans 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.
They will receive help from Republican Gov. Bob McDonnell, who reported earlier this week that his political action committee, Opportunity Virginia, had nearly $3 million in the bank, and Lt. Gov. Bill Bolling, whose campaign committee announced Thursday that it had $676,766 cash on hand.
Figures from the fundraising period, which are due Friday, are not yet available for Senate Democrats.
In 2007, Senate Republicans raised $212,536 during the same period and had just $652,001 cash on hand.
