Dem super-PAC ad hits George Allen on spending

This is the third ad the group has aired in recent weeks; it has also been up defending Sens.

Allen's campaign fired back against the ad. "Tim KaineTim KaineKaine predicts race will be 'close right up to the end' Kaine participates in Native American powwow Sunday shows preview: Both sides gear up for debate MORE's allies can try to reframe George Allen’s record, but Virginians are looking for a leader with a record of proven pro-job-growth solutions, not the same tax and spend policies Tim Kaine has championed as Governor and as President Obama's hand-picked Chairman of the Democratic National Committee," said Allen spokesman Emily Davis. "This negative Washington ad is just more evidence that Tim Kaine wants to be a Senator for President Obama, but George Allen will be a Senator for Virginia."

The ad comes on the heels of an ad from the Republican-affiliated outside group Crossroads GPS that attacked Kaine and is running in the same media markets: Washington, D.C., Richmond and Charlottesville. The group said the ad buy size rivaled Crossroads's, which was a substantial buy.
