Hillary refuses to debate

Here, a Clinton match-up is highly likely to be an unmitigated electoral disaster, whereas a Sanders candidacy stands a far better chance. Every one of Clinton’s (considerable) weaknesses plays to every one of Trump’s strengths, whereas every one of Trump’s (few) weaknesses plays to every one of Sanders’s strengths. From a purely pragmatic standpoint, running Clinton against Trump is a disastrous, suicidal proposition.
