His unfavorables are pretty high and it is still really early in the process.
The last few times "anti-establishment" candidates have jumped out to early leads, they faded fast
Maybe overall, but I would question if his unfavorables are that much with Conservatives, even though I've read as much in Liberal publications, and everyone know where Fox News stands on him. I don't get too caught up on that nonsense as it's clear the establishment Republicans are doing everything in their power to smear him.
