Sanders and turnout

I expect Sanders to do well in the 3 caucus states tonight but not because, as their campaign asserts, he does well when there is high voter turnout.
An article in my local (Columbia, SC) paper today says that he does best when "there is almost no turnout."
As example, he received 18,640 votes in winning the Idaho caucus. Clinton's margin of victory in my home county alone was more than that (she received 39,322 votes).
For those keeping score nationwide, Clinton has thus far won 8.9 million votes to 6.4 for Sanders.
Sounds like a pretty favorable stat for the General Election.

This was the only forum where I could post this without it being overrun with people basically disenfranchising all black and Southern voters to discredit the fact that Hillary is on her way to the nomination and the White House.
