He had regular nationwide coverage. The real issue was the news media was almost exclusively covering anything Trump did and largely ignored the other candidates. Hillary won the primary because progressives and leftists mostly don't vote. But democrats do, and the democrats that vote in primaries are certainly not voting for Bernie. So, had the leftists and progressives took part the primary Bernie may have won. As it is they didn't and he didn't, anything else is cope. America mostly thinks leftists and progressives and socialists are as bad or worse than actual nazis because bOtH sIDes and enlightened centrism and the fact that American culture is fascist as fuck in general. This is America, and it shouldn't be surprising that Bernie didn't even come close and yet here we are. He fucking soundly fairly lost.
