Namely Cornel West, Donald Trump, Jason Palmer, Jill Stein, Joe Biden, Marianne Williamson and Robert F. Kennedy Jr. are the only remaining candidates in the Presidential Candidate Selector (see link). The Libertarians have not named a candidate yet; reportedly RFK Jr. is considering running as a Libertarian.
I also updated the questions to comport with what polls say are the issues that Americans care about most.
