So true.  But you forgot about Jerry Brown.  Here's a politician that rejected riding in the Governor's limo (perviously owned by J. Edgar Hoover!) and living in the suburban Governor's mansion back when he was first Governor in the late 70s. Instead he opted for a Plymouth that he drove himself and an apartment a few blocks from the capitol.  This is a person for the people. 

And so far Jerry's only spent about $500,000 on his bid for Governor.  He says he plans to run a frugal campaign, just like how he'll run the state.  Frugal doesn't sound too bad to me: conserving money (in the right places, like cutting prison spending), conserving energy, conserving the environment.
