It's pretty bad when Putin of all people has to school the DNC on how to hold democratic, transparent elections.
Ignoramus let me explain something to you, democracy is not defined by people merely voting. Democracy as explained by political scientists is when country has true, competetive political opposition. Russia doesn't have that and is in effect a semi-totalitarian oligarchy.
Putin, like all two bit totalitarians cares first and foremost about holding on to power. That is why instead of stepping aside at the end of his term he has put in a puppet to keep his seat warm for a few years and then resumed his well kept throne once again.
For all the pretense to valuing democracy, fact is that his party has been running Russia for 18 years with no real opposition and news organizations in Russia are still state-owned propaganda outlets.
