Though it's not like Sanders hasn't received any media coverage at all, we have to agree on the fact that Hillary not only receives far more coverage than him (whether it's positive or negative), but also that she's also the official punching bag of the GOP. Plus they are early polls, it's not like they are going to matter in months.
They matter if they are being used by candidates in a primary for electability arguments. Basing a campaign around the idea that a certain candidate polls best against Republicans, and then dropping in the polls against Republicans, could backfire with primary voters.
