Come on MM. Ditka is well known for his outbursts, except this isn't football. Politics takes a certain demeanor. Bad behavior won't work. Ditka is a larger then life force and a Republican. I don't know how conservative he is. But making a stink about a report by Matt Drudge, shouldn't get you upset.
Politics requires a certain demeanor usually. Some people can get away without having that demeanor. Hillary is one...no matter how much she sounds like a fishwife, the media only covers her calm statements.
In the case of Ditka, he will be one who can rant at the press without paying the price. Everyone already knows he has a temper and doesn't like the press, and they still are supportive of him running. It's that "regular guy" thing, which certain politicians can use to their advantage. Jess Ventura used it to get elected. He was a poor governor, but he was great at getting elected.
In the case of Ditka, I imagine he would be a great campaigner, but would probably get fed up pretty quickly having to deal with the likes of Carl Levin and Joe Biden. He probably would only last one term, but that is ok with me. He would hold the seat in the Republican column and make the democrats spend a lot of money in Illinois, even if he loses.
