While Kaine supported the compromise, he's since said he wants to see the looming defense cuts replaced by other measures — and has attacked Allen for failing to lay out a concrete plan to do the same.
"George Allen was willing to let our government default on its obligations rather than join his own party's leaders in a compromise — a position that led to a downgrade of our nation's credit rating. So, it's not surprising that the ideas he's furthering make deep defense and domestic cuts, more likely, not less," said Kaine spokeswoman Brandi Hoffine. "While Tim Kaine has put forward a bipartisan, workable solution to avert this crisis, George Allen is pushing measures, like the 34th vote to repeal the Affordable Care Act, that would actually add to the deficit and further gridlock our government in yet another partisan battle. The last thing Virginians want is to rehash the past, which is exactly what George Allen has called for."
Allen has been hitting Kaine hard on the issue in recent weeks, and it's also become a major point of contention between Mitt Romney and Obama in the state.
The two are locked in a tight Senate race, though Kaine has had the edge over Allen in most recent polls. The two will debate Monday evening.
