Why is Hillary doubling down on attacking a Dem candidate?

117. but you see, I think that's just the problem.

No one seems sure who the Democrat is.
In words, Joe and Bernie seem to be exactly the same on policy - except for single payer. And student debt. But in each case, and more, like zero carbon emissions and immigration and and - they both agree on what the end game is. They are very much the same in this, as are all the Dem candidates.
But having a dream as a floating out there ideal (that would be Biden) and as something to tackle and take a bite out of (that's Sanders) are significantly different positions on the team.
superbowl metaphors to be filled in later, as I know nothing about football

Go get the 45 fucker! Both of ya - all of ya! Go! And on your way, figure out who's got the best game plan, but it's all heading in the same direction beyound the years of plank head. (he does have a rather vertical profile)
