I followed him when he was vying for the Senate seat in NJ, when he was still mayor of Newark. The dude had one of the most progressive messages I'd heard of, that's why he appeared on my radar at the time. No doubt why he climbed the political ladder so quickly. He's positioning himself for a 2020 run for president. He knows he has to toe the line between corporatist and progressive, that's why he ended up recruiting Sanders, the most popular politician in the country, especially among progressives, to draft an alternative resolution with the exact same safety standards he'd initially voted against. I'm sure he thinks if he get's Sanders on board, his progressive base will follow and they'll drop the opposition to his initial vote against it, just like, as you can see, Buck has been pushing.. (But he supports lower drug prices, too, see!")..
