Kristof is wrong that Sanders' supporters agree with Clinton on much of anything, if you look at her history. This is a woman who supported so-called welfare "reform" in 1996, when her husband signed the bill, which was all about kicking poor women off of welfare. Until Sanders started pushing against so-called "free trade" bills, Clinton and her husband supported them, as has Obama. Clinton is a supporter of corporations and Wall Street. Like her party for the last 20 some years, she has been opposed to the interests of working-class people. 

And she is widely known as an interventionist hawk on foreign policy, even more so than Obama. She will advance the Democrat-Republican policy of perpetual war in order to conquer the Middle East to support the business interests of US-based international corporations.

Sanders will make his own decisions, and we will make ours. I won't vote for Clinton. As a working-class person and war opponent, it's not in my best interests.
