Take That, Mr. Potty Mouth

Norm Coleman just released a broadcast ad that's a bar of soap aimed right at Al Franken and his filthy, filthy mouth.

The intro features a wan, deeply concerned Coleman bracing his fellow Minnesotans for 30 seconds of bleeped-out Franken rants, freak-outs and snide, off-color asides:

"I approve of this message (pause) because I thought it was important for you to see it."

Coleman's aim: to portray Franken, a comedian and writer, as an angry, ill-tempered outsider who is fundamentally un-Minnesotan.

The hard-edged approach comes after a bevy of news articles highlighting Coleman's relationship with a GOP operative who rents the senator a room and toilet for $600 a month.
