Biden allies wants Sanders out, sooner rather than later

[beastie boy]

8. In the near future, Bernie staying in the race is not Joe's problem. It's Bernie's.

The longer he stays, the more he discredits his motives and his character.

The results of the primaries keep showing that Bernie is incapable to mount an effective opposition to Biden, like he did to Hillary in '16. the vast majority of Democrats are much more skeptical of Bernie than they were in '16. The vast majority of Democrats want Trump out. A diminishing minority wants Bernie in at Biden's. With time, this minority is sure to decrease, likely to the point where they no longer represent a threat to Biden or a bargaining chip for Bernie to use at the convention. If this continues to be the case, Bernie will be forced to endorse Biden without getting anything of value in return. Not endorsing Biden by the time he is nominated would be political suicide for Bernie and his movement, and Bernie knows it.

While many Democrats find it annoying that Bernie refuses to accept the inevitable, the end game will change little, and the changes will not be in Bernie's favor. Like a poker player who keeps raising the stakes with a losing hand, eventually Bernie will have to make a call. And the longer he waits, the more he will lose.
