Sadly they have success based on fear.
The Liberals and Democrats have been able to scare people that Republicans are racist sexist homophobic Etc.
So they’ve been able to scare people, that since Republicans are so repulsive, they need to find their political home in the Democratic Party.
Why do 90% of black voters vote Democrat year after year? I think fear of Republicans motivates that voting behavior.
(vote Democrat year after year?)
Look no further than unearned entitlement programs.
