Presidential Candidates Previous Jobs

Before the many candidates for the 2008 election became office-holders, they had jobs that were very hardworking and some disgusting.
Democrat Hillary Clinton had to spoon guts out of fish and wash dishes at a national park while Republican Mike Huckabee cleaned the floor at JCPenney and had a gig on the radio.
Mitt Romney worked on a ranch in a sewage pipe.
Republican Fred Thompson stated "I've worked in a factory, I was a bouncer at my uncle's drag strip, I worked at the post office, I sold children's shoes, I sold ladies', I sold men's clothing, I was a night clerk at a motel."
Democrat John Edwards worked at a textile mill where he "cleaned out overhead in the weave room, which is where all the crap goes."
Republican John McCain stated "I've never really had a bad job."
Democrat Barack Obama worked at a construction site. He also said that "his worst job was scooping ice cream at a Baskin-Robbins because he ate too much of it."

I thought that this was kinda of funny at first but then I realized that it showed how hardworking and dedicated the candidates were.
What do you think about these jobs? What does it show about the candidates?
