In a nice bit of television today Elizabeth Edwards called in to hardball to politely ask Ann Coulter to stop making personal attacks against candidates. It reminded me of John Stewart's Crossfire appearance where he too asked that commentators raise the level of political dialogue.
Now, I'm not sure if these requests really do anything to improve the level of political discussion or not, but it definitely draws attention to the theatrical quality of some of this political entertainment (in case there is anyone left who doesn't think Ann Coulter is theatrical, I suppose). Perhaps pointing out how unproductive personal attacks are is fruitful in itself. If nothing else, it helps politicians separate themselves from entertainers by emphasizing their own seriousness.
Barack Obama is still my candidate, but I'm growing more and more fond of Ms Edwards.
