Obama and his team don't take Bernie seriously. Which is why if Bernie looks like he's going to win the nomination, then it'll be all hands on deck to stop him. But they aren't planning it as they are sure that Bernie won't get close to sniffing the nomination.
It's a big gamble by them because I can easily see them being caught blind sided.
I get frustrated by the coverage Bernie gets whether its hostile, pretending he doesn't exist or attacking him through Warren as a proxy...
but I'm now of the belief that this is a good thing. It might be an advantage that cable news and elite Democrats don't take him serious this time around and think he'll flame out. Since he's getting ignored, he's gone almost untouched of attacks during the primary.
Pretty much every candidate from Beto, Kamala, Pete, Warren, Amy, Biden and now Bloomberg got media hype but then naturally got backlash once they moved up in the polls. Bernie's unmovable base and steady rise is a benefit. He's already got great favorables, people just think Biden is more electable and hopefully that changes peoples minds if Biden finishes 4th in Iowa.
