Uh, ok if you really mean that you should bet a ton of money on Biden... I agree with you, fwiw, but saying that polls months out from an elections are more predictive than bettings lines is very questionable logic, especially when most people say their mind isn't made up yet. We'll see what the polls say in January.
Biden's momentum will pick up after South Carolina? You realize that South Carolina is fourth, and takes place 26 days after Iowa. That's a long negative media cycle if he gets hammered in IA, NH, and NV.
And Bernie has no chance. His chance was 4 years ago and he blew it. His only role now is blocking Warren from getting the nod and helping Biden get elected. Biden should give him some sort of ambassadorship as a thank you
