Devine is a long time party insider. He's been running Democratic campaigns for decades and actually played key role in creating the super delegate system back in the early 1980s. Weaver meanwhile, as far as I know, has only ever worked in politics for Bernie Sanders. He's run his campaigns, was actually his campaign driver at one point way back when; he ran his House and Senate offices.

These days when he's not running Bernie's campaigns he runs a comic book store in DC. Really. That's not snark. He has a comic book store in DC. So this is very much eye of the beholder. Is Devine someone with a bit more perspective of what's at stake in November, a bit more rein on his emotions and a bit less inclined to blow up the Democratic party if his candidate doesn't win? Or is he a Democratic party guy who wants to be running campaigns in the future, regardless of what happens with Sanders' 'Revolution'? Again, eye of the beholder.

So I suspect there is some cleavage here. And in any case, if Weaver's a Bernie before everything loyalist and not used to being on TV, that might be a reason not to have him on TV. Regardless, some good insight into how campaigns works.
