Dropping out because the family business needed attention? Dropping out of college to save the family farm or store would be noble. Dropping out to start a business that succeeds? One shows that a degree isn't that necessary. Dropping out and returning? Colleges often suggest that. Dropping out to serve in the Armed Services in wartime? We don't see that very often today. Dropping out because one can't afford to continue? That could be more commonplace -- among Presidential candidates born around 1980 or later -- and excusable.
Dropped out due to bad grades? That could be a question of qualifications. Expelled for ethical misconduct such as cheating on exams or trying to rig a student election? Moral turpitude.
Character may not matter in a safe seat, but nationwide it matters greatly. Character flaws are enough to solidify the partisan opposition and enough to give many independent voters cold feet about voting for one.
Character certainly didn't matter in 1992. In fact I recall the slogan "Character Doesnt Matter"
This isn't 1992. Besides, the issue with Bill Clinton was with sex, and not with integrity of elections in which he participated.
Walker lies. He cheats. He gives out-of-state interests the opportunity to bleed Wisconsin.
