IDK why Quinnipiac is suddenly recognized as a horrible pollster? (my guess? Shills be shillin) It's pretty clear that Carson has been leading by double digits in a lot of states, why would it be shocking that Ben Carson is only down 2 in Connecticut?
Quinnipiac threw out some extreme polling in 2014, and they continue to poll as if it's 2014. My opinion is that they poll badly this far out and only start getting in line with reality as the election nears.
