(CNN) – Democratic frontrunner Tim Kaine took in $1.65 million in the fourth quarter for his Virginia Senate bid, his office announced Tuesday.
The former governor, now in a heated race against Republican frontrunner George Allen, finished the year with $5.2 million raised and $3.3 million in the bank.

"I'm overwhelmed and sincerely grateful for the enthusiastic support we've received in the first nine months of this campaign," Kaine said in a statement.
His fourth quarter numbers outpaced Allen's campaign, which reported $1.1 million for the same time period and $4.5 million raised for the entire year.
Kaine's campaign also holds a $1.3 million cash-on-hand advantage over Allen for the fourth quarter.
Kaine left his job as chair of the Democratic National Committee in April to launch his Senate bid.
Meanwhile, Allen, who once held the Senate seat before losing re-election in 2006, kicked off his campaign three months prior in January of last year.
With two former governors vying for the seat–soon to be vacated by Democratic Sen. Jim Webb–the race has already drummed up heavy attention and polls show the two candidates in a close match.
Both Charlie Cook and Stuart Rothenberg, non-partisan political handicappers, rank the 2012 Senate contest as a toss-up.
