Problem is who are you going to vote for as an alternative.  We are a one party banana republic.  All these guys for the most part got into politics to benefit themselves, so changing the horses does not change much, sad to say.
Term limits for all elective office (two term limit) and no running for any other elective office for five years may be our only hope.  Also no benefits like retirement pensions for those in elective office.
You serve and get out and let someone else give it a try.  No more professional politicians.  Lack of experience is not a problem.  Look at where having experienced politicians has gotten us. 
Can things be any worse or corrupt  as they are now.
