Jerry Bader found the last interview Dick Leinenkugel did as a candidate, done with the Milwaukee Journal Sentinel. Leinenkugel blamed talk radio for his demise, and claimed the GOP needs to “broaden” the party.
I would say that actions such as endorsing combined reporting (done after he entered the race) and being a key part of the Dirty Talgo Deal did more to torpedo his campaign than simply being the “token opposition party Cabinet member”. Of course, talk radio is what brought those actions out of the memory hole.
