Labor Day marks the unofficial start of campaign season, but the 2020 presidential election is well underway. A total of 25 Democratic candidates announced their intention to replace Donald Trump as president. But after two debates during the summer, five have already dropped out of the race—Senator Kirsten Gillibrand (D-NY), Representatives Seth Moulton (D-MA) and Eric Swalwell (D-CA), Governor Jay Inslee (D-WA) and former governor John Hickenlooper (D-CO). More are expected to follow in the coming months. 

The first fall debate takes place in Houston on September 12, but out of the 20 remaining Democratic candidates, only 10 will be present. In order to qualify, they had to receive 130,000 individual donations and poll at 2% or higher in four polls approved by the Democratic National Committee. 

Here's who made the cut and where they stand on issues, like gun control, climate change, student loan debt and health care. 

1. Joe Biden

Former vice president; former U.S. Senator from Delaware

State: Delaware

Biden has an education plan that proposes to make two years of community college or technical school free while also relying on the federal Public Service Loan Forgiveness program to help teachers with their student loan debt. He has called for a ban on assault weapons and favors federal criminal background checks on the sale of guns. Biden does not support Medicare-for-All but has said that he agrees with slowly improving the Affordable Care Act to expand coverage to the uninsured. 

2. Cory Booker

U.S. Senator from New Jersey; former mayor of Newark

State: New Jersey

Booker has supported Medicare-for-All and a public insurance option that would establish a government-run health care plan as an alternative to private insurance. On guns, Booker has a plan that is the most restrictive of the Democratic candidates, proposing that gun owners pass background checks and obtain a license to possess a firearm. He also supports the Green New Deal and has backed climate change legislation, which would give up to $25 billion a year to the Agriculture Department to create new jobs, plant billions of trees and restore coastal wetlands by 2030. 

3. Pete Buttigieg

Current mayor of South Bend, Indiana

State: Indiana

Buttigieg's platform includes support for a Medicare-for-All national health insurance plan, a student loan forgiveness plan that provides debt relief for borrowers in exchange for national service and a cancellation of loans altogether for students who attended career training programs at for-profit colleges. His gun control plan proposes to invest $1 billion toward solving gun violence, which would go to law enforcement agencies and local leaders while also banning assault weapons and requiring criminal background checks for gun owners. 

4. Julián Castro

Former U.S. Secretary of Housing and Urban Development; former mayor of San Antonio

State: Texas

Castro supports universal healthcare and has an ambitious housing plan to put "people first," which also addresses climate change. The plan would invest $200 billion into a green infrastructure fund that would go toward improving public transportation, installing electric vehicle charging stations and reducing greenhouse gas emissions. Castro's education plan calls for free tuition at all public colleges and universities while also forgiving student loans for those who receive food stamps and Medicaid. 

5. Kamala Harris

U.S. Senator from California; former district attorney of San Francisco; former attorney general of California

State: California

Harris supports the establishment of a Medicare-for-All national health insurance plan, along with reforming the current student loan system by capping federal student loan interest rates. She has also called for criminal background checks for gun owners and wants to prevent those convicted of federal hate crimes from being able to buy guns. She is also a supporter of the Green New Deal and was the first to endorse it during the June Democratic debates. 

6. Amy Klobuchar

U.S. Senator from Minnesota; former Hennepin County, Minnesota, attorney

State: Minnesota

Klobuchar believes that the Green New Deal is unrealistic but supports other simpler efforts to combat climate change. Her platform includes common sense gun control (in the form of universal background checks) and reducing health care costs. She does not support Medicare-for-All but does want to expand coverage and make a government-run health plan available for those who want it. 

7. Beto O’ Rourke

Former U.S. Congressman; former candidate for U.S. Senate

State: Texas

O’Rourke supports student loan forgiveness for teachers who have worked for more than five years in a public school, with a reduction in loans for those who work in public interest jobs. He wants a complete ban on assault weapons and supports a federal buyback program to get them off the streets. His climate change proposal includes the reduction of greenhouse gas emissions in the next 30 years, as well as development grants for communities impacted by changes in energy and the environment. 

8. Bernie Sanders

U.S. Senator from Vermont; former U.S. Congressman; former mayor of Burlington, Vermont

State: Vermont

Sander’s signature campaign issue is Medicare-for-All, and he has worked to pass universal health care legislation in the Senate. His plan guarantees no-cost coverage through a government-run health plan and would virtually eliminate private health insurance altogether. He also supports free college tuition and the cancellation of all $1.6 trillion in existing student loan debt. His position on gun control is to ban the sale of assault weapons, require background checks for gun owners and institute a federal government buyback program for assault weapons. 

9. Elizabeth Warren

U.S. Senator from Massachusetts

State: Massachusetts

Warren's platform includes Medicare-for-All and the elimination of private insurance plans. She has proposed an ultra-millionaire tax, which would cover the cost of 4 years of attendance at public universities and colleges, in addition to a student loan forgiveness plan, which primarily eliminates debt for low- and middle-income workers. Her ambitious gun control plan proposes to reduce gun deaths by 80% through executive action and legislation. 

10. Andrew Yang

Businessman and tech executive

State: New York

While Yang believes in canceling some student debt, he does not believe that public education should be free. Instead, he supports working with schools that receive public funding to keep costs down, in addition to other financial measures. His plan to combat climate change includes nearly $5 trillion in spending over 20 years, including limiting the influence of oil, gas and coal lobbyists and moving people in areas prone to coastal flooding to higher ground.

Look out for these 10 candidates to take the stage September 12 to discuss these important issues and more.
