For much of the last two years many Democratic insiders and pundits, including me, viewed Bernie Sanders as a less formidable candidate for the Democratic nomination in 2020 than he had been in 2016. In a multi-candidate field, according to this argument, Sanders voters would be dispersed among many different candidates who, like the Senator from Vermont, were not Hillary Clinton. It may be that in 2016, it was not Sanders who consolidated the anti-Clinton sentiment, but Clinton who consolidated the anti-Sanders sentiment. For many Democrats the idea of Sanders winning the nomination and the ensuing general election campaign between Trump and Sanders is concerning. This puts Democratic voters and the party leadership, such as it is, in a quandary.
