Some proof that there is no such thing as pay-to-play in the party of the wealthy ruling class, would be if Hillary and Bill were to keep being paid over 200k per speech by the likes of Goldman Sachs and UBS now that their political power/influence has be diminished.  If the market value of a Clinton's speech plummets now, then the pay-to-play conjecture can be reduced to a fact.  The same goes with the pay-to-play foreign donations to the Clinton Foundation.  

Simply stated the problem with the Democratic Party's platform is/was: You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time.  The Democratic Party has been having problems fooling folks lately.  Let's see if the Republicans can do a better job of fooling us!
