One of the big questions heading into the Democratic National Convention late last month was whether Hillary Clinton could rally Bernie Sanders supporters to her side. Before the convention, many Sanders supporters saidthey would support Clinton in a two-way matchup against Donald Trump, but when pollsters offered them third-party candidates as an option, they abandoned her.
Then, on the first night of the convention, Sanders gave his big speech urging his voters to support Clinton, and we can now see that the convention did help persuade some Sanders voters to switch. But about a third of Sanders’s voters are undecided or still going with a third-party candidate when given the choice.
