I have no idea if the poll is designed to push public opinion. But CBS & NBC has the race near margin of error. He had a lead in the state for a long time, heavily black democratic vote, so it does look like he’ll win.
Now, super Tuesday will present a problem. A lot of big liberal states voting. So, his enjoyment might be short lived.
East Carolina U. Biden +8
PPP Biden +15
Clemson Biden +18
CBS News/YouGov Biden +5
NBC News/Marist Biden +4
Bernie Sanders feels like one of the biggest paper-mâché frontrunners I've ever seen. People are acting like he's inevitable? What's he won thus far, seriously? He lost Iowa delegate-wise to Pete Buttigieg. He won by one whole point in New Hampshire, a state that borders his home state and in which he cleaned up in 2016 (with over 60% of the vote that year), only to plummet to getting not even half that percentage in 2020, not to mention he tied in delegates won in that state with Buttigieg. He did win Nevada pretty nicely, but it was another damn caucus, and as we saw in 2016, Bernie does a lot better in caucuses than primaries (see: New Hampshire this year, he'd have done a lot better had it been a caucus state.)
I am really not buying the "Bernie's running away with it!" narrative at all... at least, not right now, as I type this, anyway. Of course that will probably change if Sanders does indeed do really well on Super Tuesday.
