Already starting to be concerned for my Sanders bet and considering buying out of it when an opportunity arises.
I never anticipated that Warren's polling would come up this high. She dropped off a cliff after the DNA test gaffe, but she's made a huge rebound. I think the biggest threat to Sanders is a viable "progressive" alternative. Other than Gabbard, Warren is the only candidate who I can see the Sanders base defecting to. In their eyes, she can actually edge him in pinning down her ideas to specific policy proposals.
As for Biden, I'm still bearish. He had an excellent roll-out, but I think the debates will tear him down. That's where I expect Buttigieg to steal many of his supporters through superior articulateness, youth, and less baggage. I think Buttigieg's "I won't tell you what I stand for" approach is also genius. I figure he can avoid attacks on that point by virtue of the other big-namers focusing their crosshairs on Biden, similar to Trump in 2015 and early 2016.
I also think the chance of a contested convention is high, and things are definitely going to get ugly.
@Jack V Savage , hope you'll visit us from time to time over here. It's more civil and productive than the War Room.
