Democrat Tim Kaine is outraising his Republican opponent, George Allen, in Virginia's Senate race, but a conservative outside group is stepping to Allen's aid with $1.1 million in new television ads attacking Kaine as a big spender.

Campaign finance reports Kaine is filing show that he raised $3 million from April through June compared to slightly more than $2 million Allen raised in the same quarter.

That leaves Allen with about $3.3 million in the bank four months before the Nov. 6 election that could determine which party rules the Senate, and Kaine with $2.7 million on hand not counting $3.5 million already paid to reserve television ad time.

The pro-Republican Crossroads GPS, which does not identify its donors, is airing the ads attacking Kaine's stimulus package support.
