His chief rival for the GOP nomination, Attorney General Ken Cuccinelli, has not yet released his fundraising totals. Candidates must file by Monday.

“I am very pleased by the strong financial support I have received from Virginia’s business leaders and other friends and supporters from all across our state,’’ Bolling said in a statement. “They ... know that to retain the governor’s office we have to nominate an electable candidate, and I am the only Republican candidate for governor who can energize and mobilize the base of the Republican Party, while at the same time reaching out to the independent voters whose support you must have to win statewide elections in Virginia.”

Democrat Terry McAuliffe, who will announce after the November elections, has not begun raising money.
