Barbara Radnofsky is spending six figures on a three piece mailer to statewide triple Ds. Normally, I wouldn't advocate announcing the details of your campaign tactics in an campaign e-mail, but when you are campaigning against Gene Kelly, I think we can understand this is a special case.
In fact, you can see her mailers online! (all in pdf format)
My favorite part is the smell 'negative' part. But when you are talking about Gene Kelly, it's more amusing than anything else (in the sense 36% of Democrats voted for him...)
