There are much better ways to handle this smear campaign -- rebuking the ads is certainly fair, but it doesn't appear that Hagan nor her campaign are doing so for the right reasons.
It shouldn't be that Kay Hagan really is a "good, God-fearing Christian," but that she seeks to represent North Carolinians of ALL backgrounds. My inkling, however, is that atheists are considered an expendable demographic. Replace this with any of the other, similar, base accusations made all over the country during this campaign season where the name of one voter base is being used as a pejorative to scare another. ("No, ma'am, [he's not an Arab], he's a good, decent family man.")
Atheists? It could be worse, huh? She could have been caught "pallin' around with those Muslim Arabs and Terrorists!" I'm disappointed in Kay Hagan, Elizabeth Dole, and North Carolina. Most importantly, though, I'm disappointed in America.
This isn't the country my teachers gave me so many reasons to be proud of.
