While Sanders and the bombastic Trump stand far apart on many issues, both have consistently railed against entrenched politicians and trade deals that they say hurt American workers. Trump made his latest appeal Monday night after Sanders' endorsement of Clinton and call for party unity to defeat Trump.
Fowler and several other Sanders backers who gathered in 90-degree heat here Tuesday believe Trump's recent olive branches to Sanders voters will fall flat. However, the activists who showed up here may not capture the feelings of all the roughly 12 million people who voted for Sanders in the Democratic primaries.
Near a "Bernie or bust" rally across from Philadelphia City Hall on Tuesday, Fowler said he will vote for Green Party candidate Jill Stein rather than Clinton or Trump. Lisa LeVally Evans, another protester from Ohio, said she is "afraid" of both major party candidates and could never bring herself to vote for Trump.
"I think the true Bernie supporters can never do that," Evans said, adding that she plans to vote for Stein.
Joel Bradshaw, a 39-year-old lifelong Democrat, said he could not support Trump because of his rhetoric.
"We need less borders in this world, not more," he said.
Most Sanders voters will still likely support Clinton in November. But if some vote for Stein or abstain altogether, they could indirectly aid Trump by sapping votes away from Clinton.
