U.S. Chamber goes last-minute negative on 'baby' David Perdue

David Perdue's tussle with the U.S. Chamber of Commerce, we surmised, was timed so the Chamber did not have enough time to drop a negative ad.

Well, on Election Eve, here comes the Chamber with an ad blasting Perdue and pumping Jack Kingston as voters go to the polls. It even stole his baby theme. Here's the script:

"Well, he sought our endorsement several times but didn't get it. Now, losing and desperate, David is crying like a little baby.

"The U.S. Chamber of Commerce proudly stands with conservative champion Jack Kingston. This Tuesday, get out and vote."

Two takeaways: 1. The Chamber really, really does not like Perdue. 2. Such a late move is another sign that this is a very close race.
