During your presidency, you will be faced with a robotic revolution — for example, driverless cars and semitrucks — as machines take skilled and unskilled jobs from Americans. This will further hollow out the middle class and divide society. What do you propose we do as a nation to bridge the gap without stifling innovation? And what will you do as president to create a country where everyone has upward mobility?

At present, the United States lacks the ability to send humans into space. If elected, what would your space policy be? Would you work to foster commercial space flight? What directives, if any, would you give to NASA? And, most importantly, what would you do about NASA’s budget?

Shonda Rhimes, creator of ‘Grey’s Anatomy,’ ‘Private Practice’ and ‘Scandal’

There is so much divisiveness is our government today. Achieving anything of substance seems impossible because compromise seems impossible. What do you think needs to be done to unite Congress so that they are working more for the good of all of the American people as a whole and less for the good of the partisan interests that seem to have currently halted any hope of legislative change or progress?

Sir Elton John, singer and activist

In spite of great progress, HIV/AIDS is actually dramatically on the rise in the U.S. South. What would you do as president to help stop this epidemic, particularly among minority communities?

How can we shape a foreign policy that fosters appreciation for American values instead of resentment of American privilege? Can cultural diplomacy be revived to achieve this goal, so that our role on the international stage will feel generous rather than self-interested, will lead by inspiring example rather than by force?

Julianna Margulies, actress

Next year, the citizens in Nevada will vote on an initiative to require the same Brady background checks that are conducted at licensed gun dealers to be conducted for sales made at gun shows and online. Do you support that initiative and, as president would you seek to make it federal law?

David Axelrod, former adviser to the President

What is the difference between a Social Democrat Progressive and a Constitutionalist?

Given the awesome responsibilities of the office and the demands — physical and mental — should there be an age and health requirement to be president?

Buzz Aldrin, astronaut

A vision-focused, well-funded American space program represents U.S. global leadership, adds to the country’s technological strength and promotes educational excellence. As president, what is your plan to re-build and re-energize America’s space exploration agenda?

Billie Jean King, tennis champion and founder of Billie Jean King Leadership Initiative

What programs would you put in place to stop discrimination in the workplace, specifically, on problems related to inequality and lack of inclusion based on gender and sexual orientation?

Dick Cavett, talk show host

In the recent Republican debate, many Republican candidates couldn’t think of a single American woman, in 240 years of our national history, deserving of being pictured on our $10 bill. Jeb Bush actually suggested putting a former British prime minister on American money. What American woman would you nominate?

Judy Gold, actress and comedian

A few months ago, I send my 13-year-old son out to pick me up some Mucinex and Nyquil. The pharmacist wouldn’t give them to him because he’s under 16. Why is it easier for him to get a gun than to pick up medicine for his sick mom?
