They're well done, as Franken doesn't try and be anyone but who he is. He is likeable in a down-home, folksy kind of way, which is the feel of these ads.
Norm Coleman, of course, immediately responded by attacking Franken's Minnesota credentials, you know, because a shiny-toothed, Midnight Toking, runway model-marrying, Brooklynite just screams Minnesota!
In any case, you can catch one ad in this post, and the other, arguably better one with his 4th grade teacher here.
I'm for Al Franken. The truely intelligent, view things with a sense of humor, life is too short not to and they view things with actions to improve things. I like action, I like Al.
