Democrats Worried about turnout numbers

"Hillary Clinton had a great night on Saturday. The Democratic Party had a terrible one.

But Democratic Party elites shouldn't be high-fiving each other. They should be very, very worried.
In primary after primary this cycle, Democratic voters just aren't showing up. Only 367,491 people cast a ballot for either Clinton or Sanders on Saturday. That's down 16 percent from the 436,219 people who came out in 2008 for Clinton and Obama. Factor in the 93,522 people who voted for John Edwards back in the day, and you can see the scope of the problem. Democrats in 2016 are only getting about two-thirds of the primary votes that they received eight years ago.
Republican turnout in the South Carolina primary, by contrast, was up more than 70 percent from 2008.
South Carolina's turnout numbers are not an anomaly. They're consistent with other primaries to date. Republicans are psyched. Democrats are demoralized.
Presidential elections increasingly hinge on each party's ability to turn out the faithful. There simply are not many truly independent voters who cast their ballots for different parties in different cycles. A big chunk of voters who identify as independents do so not because they cherish a moderate middle ground between two parties, but because they see their own party as insufficiently committed to its ideological principles. In this era, lousy primary turnout spells big trouble for the general election." HuffingtonPost
