Remember Norm Coleman's nasty ad last week? Well, I predicted people wouldn't be fooled, and it looks like I was right. After engaging in a brief round of character assassination, Coleman returned with a heartwarming human interest story, a far cry from the negative campaigning I was expecting to continue throughout the race.

I can't help but wonder why Coleman decided to back off. Has Coleman's internal polling shown a negative response to his nasty politics? His negative ad was immediately followed by a great ad from Franken; are Coleman's pollsters finally seeing a rise in the polls for Franken?

This is pure speculation, but I'm looking forward to the next round of polls to see if Coleman knows something we don't yet.

Here's the text of Coleman's new ad, via the St. Paul Pioneer Press's Political Animal:

"Wyatt was diagnosed with Wilms' Tumor, which is a form of childhood kidney cancer in February of 2004. On a routine screening, they found a spot on his right kidney. We knew that there needed to be more research done for Wilms' Tumor, because the drugs that we were using were drugs that were developed in the 1960s. We attended a meeting for CureSearch, and within two hours of being in the meeting, we knew that there was no funding for childhood cancer. We had eight meetings that day, and Senator Coleman's office was the last meeting of the day. We knew before we left his office that he was going to help us do something about the lack of funding for Childhood Cancer. And then in the months after that, Senator Coleman authored the Conquer Childhood Cancer Act. Senator Coleman is a lifeline for every family of a child who has been diagnosed with cancer. He's not just my Senator. He's my friend."
