Republicans' 2016 Presidential primary preferences look like a bunch of scribbles when graphed

The behinders in 6/14-6/18 in NBC/WSJ poll: 

• 1% - Trump, Kasich, Graham
• 0% - Santorum, Jindal, Pataki

 % of Republican primary voters who would not support a particular candidate (same poll):

• 66% - Donald Trump
• 55% - Chris Christie
• 49% - Lindsey Graham
• 45% - Rand Paul
• 44% - George Pataki

 
All to be taken with a big grain of salt.

What's the Matter with Polling? (The New York Times, 6/20/2015)

Election polling is in near crisis, and we pollsters know. Two trends are driving the increasing unreliability of election and other polling in the United States: the growth of cellphones and the decline in people willing to answer surveys. Coupled, they have made high-quality research much more expensive to do, so there is less of it. This has opened the door for less scientifically based, less well-tested techniques. To top it off, a perennial election polling problem, how to identify “likely voters,” has become even thornier.
