Timothy M. Kaine raised $1.3 million from July through September, his Senate campaign announced Thursday, besting George Allen for the quarter.

Kaine and Allen, both former governors, are the likely Democratic and Republican nominees, respectively, in the contest to succeed retiring Sen. James Webb (D). The race could well be one of the most-watched and most expensive Senate matchups in the country.

Allen’s campaign said last week he had raised more than $900,000 for the 3rd quarter. Allen had $1.8 million in the bank as of Sept. 30, while Kaine’s campaign says he had $2.5 million on hand. Kaine’s campaign has now raised slightly more than Allen overall — $3.55 million to $3.5 million — even though Allen had a three-month head-start in the campaign.

Both men spent significant time in the quarter helping raise money for their parties’ candidates in November’s state legislative races.

“As Governor Kaine takes his positive message on job creation, fiscal responsibility and economic growth through investments in our infrastructure and our workforce across the Commonwealth, Virginians are responding and showing their support,” Kaine spokeswoman Brandi Hoffine said in a statement released by the campaign.

Allen spokesman Bill Riggs responded: “It’s no surprise that Tim Kaine – President Obama’s former hand-picked Democratic National Committee chairman– is being rewarded for his years of loyally advocating for all of the President’s failed policies, which led to 32 months of unemployment above 8 percent, while running up our national debt.”
