RATS don’t care about the issues. They only care about who is going to steal the most for them. Being a crook is an asset to them.
The 'elite' white part of the democrat base cares a lot... but there aren't that many white liberal elites outside the DC area... and very few that don't back Bernie.
The South Carolina 'firewall' for Hillary is African American and I doubt that many of them watched the democrat debates. If the press wasn't biased - weighted down with hatred and double standards - they would tell us. But the truth doesn't fit with their world view.
Remember the fuss the MSM made about the education level of Trump's backers? And the equally NONEXISTENT fuss made about the education and social class level of Hillary's supporters? Much of the democrat base consists of the uneducated black underclass - and that isn't something the press wants mentioned.
Why? Bias and an unwillingness to acknowledge white liberal elites are propped up by the lower classes...
