Ahead of the first Democratic presidential debate Tuesday night, CNN asked several celebrities what they would ask the candidates if they had the chance.

Their answers are below.

Katy Perry

“With the GOP crusade to defund Planned Parenthood momentarily deflated, how do you intend to consistently protect American women seeking the legal, affordable health care that they so desperately require?”

Demi Lovato

“What’s the biggest issue with our health care system when it comes to mental health care, and what specifically will you do to fix it?”

Ashton Kutcher

“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? What will you do as president to maintain a country where everyone has upward mobility?”

Shonda Rhimes

“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?”

Elton John

“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?”

Buzz Aldrin

“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 rebuild and re-energize America’s space exploration agenda?”

Montel Williams

“Amir Hekmati has been in Iran’s Evin prison for four years, making him the longest-held confirmed American detainee in Iran ever. He is in ill health and his father, plagued with brain cancer, has made seeing his son once more his dying wish. Is it important that this Marine veteran be returned home soon?”

Glenn Beck

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