For all his pretended persona as "middle class Joe", which he put forward again during his stump speech, Biden is well aware of the social gulf between these rotten organizations and the workers who are trapped in them, to say nothing of the millions more workers who have nothing to do with the unions at all.
"Only about a third of potential Democratic voters with a preference in the race (36 percent) say they will definitely back the candidate they now support, [while] 64 percent say they could still change their minds", CNN polling director Jennifer Agiesta wrote.

Biden responded to Trump's attack tweeting "I'm sick of this President badmouthing unions". In 2016, both Clinton and GOP candidate Jeb Bush were leading in polls at this stage of the campaign, but the state was won by Trump and Sanders in their respective primaries.

One poll question states, "In your opinion, which candidate in the Democratic field has the best chance of beating President Trump?".
Biden, who represented DE in the Senate for more than 30 years, also collected endorsements from the state's entire congressional delegation: Sens.
