Let’s hops that Democratic candidates heed Washington Post columnist Jennifer Rubin’s warning to mount a united front against Sanders, a leader in the race who, nevertheless, is clearly the candidate most likely to lose to the election to Trump, and thereby to cause the loss of American democracy. Bernie, 78, had a heart attack last fall. It’s disturbing that, although he promised to do so by now, he hasn’t released his medical records, and he brushed off inquiries as to why. I admire Bernie’s views about a lot of things. He would be a better president than Trump by an astronomically wide margin, but the most significant thing about him right now is that he’s a threat to the nation.
