The biographical article - - "Who is Scott Walker" - - in the respected National Journal is a good resource because it has links to episodes in Walker's life you don't hear much about.
Like the election he lost for the state legislature to now-US Cong. Gwen Moore, (R-Milwaukee), and the tacky, losing campaign he ran for student body president at Marquette University, which brought him condemnation on campus.
Here's how the Marquette Tribune described that election:
His sophomore year, Walker ran for president of the Associated Students of Marquette University (ASMU, the former title for Marquette Student Government). He was accused of violating campaign guidelines on multiple occasions.
The Tribune reported then that he was found guilty of illegal campaigning two weeks before his candidacy became official. Later, a Walker campaign worker was seen placing brochures under doors at the YMCA. Door-to-door campaigning was strictly prohibited.
Walker initially denied this but later admitted to the violation, which resulted in lost campaign privileges at the YMCA.
In the run-up to election day, the Tribune’s editorial board endorsed Walker’s opponent John Quigley, but said either candidate had the potential to serve effectively.
However, the Tribune revised its editorial the following day, calling Walker “unfit for presidency.” The column cited Walker’s distribution of a mudslinging brochure about Quigley that featured statements such as “constantly shouting about fighting the administration” and “trying to lead several ineffective protests of his own.”
The revision also expressed disappointment in Walker’s campaign workers reportedly throwing away issues of the Tribune after the endorsement was initially made.
Walker dismissed this, saying he had no knowledge of what his supporters did, according to a Tribune article from February 25, 1988.
