Well, the Democratic leadership has convinced the ethnic demographics that the Dem Way is the Only Way. And that is how the downfall of all those places has manifested itself.
At the end of the day, Democratic policies are all about money laundering and bribery.....absolutely nothing else. At every single level of government its only purpose is to figure out a way to generate graft, steal funds, steer contracts to friends for kickbacks, hire family members for kickbacks or sell influence.
That is what the Democratic Party and the Left, in general, is all about.
The Left also does a better job of pitching their snake oil than the Right. The Right barely pitches anything except their backsides when they lose.
