from The Conservative Treehouse:

James Clyburn and Barack Obama are the two democrats who could unilaterally remove Joe Biden by withdrawing their support.  It must frustrate Jill Biden to know The Lightbringer and the Ballot Master have that kind of leverage over her appointments at Tiffanys.

As a result of this dynamic, we remind everyone to pay close attention to how Clyburn and Obama are indicating their position.
