Bernie Sanders, according to five different opinion polls in May compared by Real Clear Politics, beats Donald Trump in every poll. However, popularity in polls does not equal delegates at the convention. Unless Senator Sanders does very well in Tuesday's primaries in California, New Mexico, Montana, New Jersey, and South Dakota, and the North Dakota Democratic caucus, Hillary Clinton is likely to be the Democratic candidate. Whether or not Sanders would run against her as an independent candidate, or whether he would support her to prevent Trump winning the election, remains to be seen.
Salon reported that Dr. Jill Stein, the presumptive candidate for the Green party, approached Sen. Sanders about the possibility of a Stein/Sanders ticket or a Sanders/Stein ticket. Salon also reported that "polls show unprecedented support for a candidate to challenge Donald Trump and Hillary Clinton."
"This week NBC found that 47% of voters would consider a third-party candidate if Clinton and Trump were the major-party nominees. In the last week, two other polls found a large minority will vote for a third party this year. Schoen Consulting found 20% of voters would vote for a third party against Clinton and Trump with 14% undecided; Data Targeting Inc. found 21% would do so with 14% undecided. (emphasis added)"
Johnson believes that many Americans are already Libertarians at heart, according to Bloomberg.
"I'm trying to appeal to the majority of Americans whom I think are libertarian, it's just that they don't know it. And libertarian, with a broad brush stroke -- fiscally conservative, socially-accepting liberal."
