Admire his resilience, even though altering the party platform is a rather pointless effort.
Clearly he's gearing up for a drop-out, evident by "we must prevent Trump at all costs."
Um, he should have been gearing up for this since the night he lost Ohio and North Carolina and Illinois and Missouri. The time for him take a breather and reflect is past. His endorsement and withdrawal are, at this point, long overdue. He's doing harm now, and I'm allowed to be pissed off about it.
The Clintons have been doing harm for decades and need to go away retroactively, but we can't all get what we want.
