Never vote for the incumbent

A way to get us out of all this is to never vote for the person in office.
Always vote for the challenger.  See to it that all elected people
stay in office for one term only.  There is no such thing as a good 
politician or bad politician.  They are good if they see it your way
and bad if they do not.  And this would certainly end the campaign 
financing issue.  Anyone with an opinion can hold office, anyone.
And even if you hate their politics, they'll be gone in two, four
or six years.  It would be quite refreshing and a total freak-out.
