Here are the candidates' positions on the 2016 election's topline issues, and where they agree and diverge.
Democrats: Hillary Clinton and Bernie Sanders
Economy and Taxes
Same: Clinton and Sanders propose raising taxes on the wealthiest Americans and using the revenue for investments in infrastructure, education, clean energy, small business and healthcare. Both favor extensive Wall Street reforms and strengthening of federal regulations on Wall Street practices and investments. Both favor of overturning Citizens United, the Supreme Court ruling allowing unlimited independent spending by corporations in elections, and are committed to comprehensive campaign finance reform and legislation requiring outside groups to publicly disclose spending.
Sanders supports taxes on Wall Street speculators and a progressive estate tax on the wealthiest 0.3 percent of Americans, promises to break up financial institutions that are "too big to fail" and wants to eliminate Super PACs.
Clinton is focused on the "shadow banking" system, which includes hedge funds, investment banks and other non-bank financial companies, and promises to increase transparency and reduce volatility, and is promoting an SEC rule requiring publicly traded companies to disclose political spending to shareholders.
Same: Both support strengthening unions and collective bargaining rights. Both also support raising the minimum wage, but using different strategies.
Sanders promises to raise the minimum to $15 by 2020.
Clinton promises to raise the minimum wage to $12 nationally and encourage states and localities to raise their minimum wages to $15 individually while also expanding overtime rules.
Same: Both support universal pre-k, kindergarten and universal childcare. Both plan to use taxes on the wealthy and Wall Street to pay for college tuition reforms.
Clinton proposes college tuition and debt reform through an expansion of Pell Grants, free community college tuition, increasing federal grants and cutting college loan interest rates.
Sanders calls for universal free tuition for all public colleges and universities, proposes cutting the federal loan interest rate by almost half, allowing retroactive student loan refinancing to lower interest levels and creating need-based financial aid and work study for debt-free college.
Defense and Terrorism
Same: Both broadly prioritize diplomacy over military intervention, and call for strengthening the Iran Nuclear Deal. Both favor targeting the root causes of radicalization in the Middle East as a way of fighting ISIS and terrorism.
Sanders favors the two state solution in the Israeli-Palestinian conflict, promises to close Guantanamo Bay and abolish torture. He favors limited military engagement.
Clinton also advocates increased accountability and more stringent rules for China and diplomatic actions and sanctions to contain and deter Russian aggression.
Same: Both candidates support strengthening and expanding background checks, closing mental health loopholes and closing gun sales loopholes. Both support the ban of high-capacity magazine and assault-style weapons.
Clinton has an F rating, wants to revoke licenses of bad actor gun dealers, repeal gun manufacturer and dealer immunity laws, pass legislation preventing domestic abusers from owning guns and make straw purchases illegal.

Same: Both support universal health care in America.
Clinton wants to expand the Affordable Care Act, crack down on prescription drug prices and increase drug company accountability.

She also wants to broaden the scope of ACA providers to meet the needs of rural Americans, including telehealth reimbursement, streamline licensing of telemedicine and expanding services that qualify for reimbursement.
Sanders wants a single payer universal healthcare system dubbed "Medicare for All" and has said the ACA does not go far enough in terms of providing healthcare. Sanders' proposal calls for a tax increase across all tax brackets, though Sanders said in the last CNN debate that the $1,000 in projected increased taxes will be offset by $5,000 in healthcare savings per year. He plans to pay for his healthcare proposal with a 6.2 percent income-based health care premium paid for by employers, a 2.2 percent income-based premium paid by households and the tax revenue from increased taxes on the wealthy, capital gains, dividends and estates.

Wade.

Sanders supports at least 12 weeks of paid family leave, paid medical leave, two weeks of paid vacation and seven paid sick days. He promises to demilitarize police, invest in community policing, increase diversity in police forces, and crack down on hate groups.
