Bernie's home stretch campaigning must prepare his loyal followers to be ready to support Hillary Clinton.

Many of Bernie's supporters are angry at the notion of compromise itself. Hillary's positions on war, money in this campaign, etc. are seen as moral failures about which no compromise is acceptable.

But, it's too broad of a statement to say that compromise itself is bad or immoral or never a good option. No relationship can survive without compromise and no politician can either. We are not absolute rulers in exclusive kingdoms but members of a polity made up of diverse and opposing opinions and we must work to find common ground to get things done. 

It took Hillary a while to learn this and Bernie too. As an office holder, he has had to compromise on just about everything he stands for--he could not have survived this long without that-- but his supporters feel this is a mistake for them now. Bernie voted for the war in Afghanistan, but not the one in Iraq. He voted against holding gun sellers liable for acts of violence perpetrated by their customers. He has taken money from individual bankers but not banks themselves. I respect these positions of his and salute his spirit of compromise as a Senator and a candidate. I do not think his campaigning against Clinton now is insincere nor inappropriate. He is making his points and driving to the convention to get the Democrats on a better political footing even as they nominate Hillary. But he should not portray Hillary as a slimeball politician; he will wind up supporting her as he should, after turning off many of his current supporters that are needed to get Hillary elected over Trump. That is a compromise he will make, after getting some policy concessions from the party and from her, and one that he needs to prepare his supporters to make as well.
