Green Party presidential candidate Jill Stein said a vote for her isn't a wasted one. It isn't a vote for Donald Trump, she said.

"The biggest way to throw away your vote is by voting for these establishment parties that have thrown us under the bus," she said. "The best way to use our vote is to invest in this social movement, this social transformation that we are creating together."

Much of this social movement, Stein mentioned, was created by the supporters of Vermont Sen. Bernie Sanders in his bid for the Democratic nominee for president. While Sanders is endorsing Hillary Clinton, many of his backers are moving to the Green Party.

Stein spoke to a relatively small group of supporters (or potential supporters) Saturday evening in a meeting room at the Birmingham-Jefferson Convention Complex. The vast majority of those indicated by raising their hand that they were former Sanders supporters.

Stein is a medical doctor and activist. She ran for president for the Green Party in 2012.

During her campaign rally, Stein thanked Alabama Bernie supporters "for blazing the trail.

"We are going to be 'Bernin' Green,' I think from here on out," she said to applause.

Lynn Richardson, of Birmingham, was one of these Bernie supporters. She said when Sanders conceded to Clinton at the Democratic convention, she didn't want to lend her support to a corporately backed candidate.

She feels the values of the Green Party, such as, "peace over profit" and social justice actually represents the majority of people.

Richardson said the Alabama Green Party formed this summer and worked to obtain the 5,000 signatures - they actually got 9,000 -- needed to get Stein on the November ballot.

She said the next step is to continue to educate voters, start local chapters and to run Green Party candidates on the local level.

Stein spoke Saturday in support of the recent Alabama inmate strike and against "legalized slavery" in American prisons. She mentioned the recent gas pipeline spill in Shelby County and its potential impact.

"They say it didn't get into the rivers, but what about the aquifers?," she asked.

Stein quoted a recent Gallup poll that showed that 57 percent of Americans want a major third party. That number is up from 46 percent in 2012.

That isn't even because Clinton and Republican presidential nominee Donald Trump are the most unpopular presidential nominees in modern history, she said.

Stein said voters don't have to fall prey to the "politics of fear" and vote for the lobbyist, corporate and Super PAC-funded candidates who don't have progressive policies.

"Hillary Clinton is not the solution to the threat of Donald Trump," she said.

Stein, who supports eliminating college debt, said if the 43 million people "trapped in predatory student debt" voted for a third party, then a third party candidate could win.

"We have the power to win this," she said.

Stein laid out her Green Party platform, such as, establishing a living wage, health care for everyone, creating 20 million jobs by transitioning to 100 percent clean renewable energy by 2030 and keeping public school systems from being privatized.

Birmingham activist Carlos Chaverst said he supports Stein because she is for creating "real change in America," instituting a living wage and speaking out against mass incarceration.

"Most of the issues she speaks on are very relatable to the people in Birmingham," he said, where the median household income in Birmingham is $31,000 and 74 percent of the population is black.
