Former Democratic National Committee chairman Tim Kaine hauled $4.5 million during the third quarter of 2012, about $1 million more than former senator George Allen (R), who brought in about $3.5 million. 

Both Kaine and Allen enjoyed their most productive fundraising quarter of the cycle. Both spent big, too. Kaine finished the period with $1 million in the bank while Allen ended with about $2.6 million in the bank, meaning they both spent more than they took in during July, August, and September. 

Kaine's campaign has invested heavily on airtime for ads, dedicating $7.5 million so far, including a recent $3 million purchase.

Kaine and Allen are both former governors and, as a result, very well-known figures in Virginia. Polls have shown a competitive race, but Kaine appears to have more momentum of late. The most recent Washington Post survey shows Kaine leading Allen 51 percent to 43 percent, after the previous two polls showed a tie.
