Donald Trump and Hillary Clinton will both announce their vice presidential running mates within the next few weeks, prior to their parties’ national conventions in late July. Several of the top contenders for the number-two slots are currently serving in Congress. Which bills have the vice presidential contenders introduced during this Congress, what does it say about their potential policies as vice president… and perhaps even as president?

Clinton’s and Trump’s likely picks

Clinton’s shortlist includes Senators Tim Kaine of Virginia, Elizabeth Warren of Massachusetts, Sherrod Brown of Ohio, and Cory Booker of New Jersey. Dark horse candidates are also believed to include Mark Warner of Virginia and Al Franken of Minnesota.

Trump’s most likely picks include Senators Bob Corker of Tennessee, Joni Ernst of Iowa, Jeff Sessions of Alabama, and Tim Scott of South Carolina. (Although Trump has been such an unconventional and unpredictable candidate that his pick is anybody’s guess. Failed 2008 vice presidential candidate Sarah Palin is on the short list, as is two-time failed Senate candidate Scott Brown, and perhaps even Trump’s own daughter Ivanka.)

Bills introduced by Clinton’s top contenders

Kaine, a 58-year old former Virginia governor and DNC chairman who Politico reported is currently the top contender for the spot, has been the lead sponsor of 21 bills this Congress including:

S. 2016, the Responsible Transfer of Firearms Act, which would criminalize the sale or transfer of firearms to a prohibited individual. Current law doesn’t penalize sellers who didn’t know that the buyer was prohibited.

S. 2256, the Co-Prescribing Saves Lives Act, an attempt to combat the growing heroin and opioid addiction/overdose epidemic through federal grants to prescribe the anti-opioid naloxone and establishing federal co-prescribing guidelines.

S. 1587, an Authorization for the Use of Military Force against ISIL. The U.S. military actions against the Islamic State have to date been carried out by the Obama Administration and not technically authorized or approved by Congress. This bill would do so for three years and repeal the AUMF from 2002 for military action in Iraq, which is still the authority the Obama Administration claims for its fight against ISIL.

Warren, the progressive Massachusetts liberal firebrand who was one of the only senators to stay on the sidelines and not endorse either Clinton or Bernie Sanders during their fight for the Democratic nomination, has sponsored 23 bills this Congress including:

S. 1709, the 21st Century Glass-Steagall Act, which would reinstate several of the provisions from the original 1933 Glass-Steagall Act that created a number of regulations for the banking and finance industries, but were repealed by Clinton’s husband President Bill Clinton in 1999. Many progressives like Warren believe that the repeal, which allowed for such new rules as combining investment and commercial banks, allowed the banks to become too large and thus helped contribute to the gargantuan bankruptcies triggering the Great Recession.

S. 2578, the Reducing Unused Medications Act, which would “amend the Controlled Substances Act to permit certain partial fillings of prescriptions,” which is currently not permitted. It passed the House in May and could likely pass the Senate soon.

S. 2789, the Tax Filing Simplification Act, which would create a free IRS-run tax preparation and filing service online. No more stressful April sessions on TurboTax if this passes.. though the lobbyists are lobbying hard to preserve the billion-dollar tax-prep industry.

Brown, the second-term progressive senator and former congressman from the critical swing state of Ohio, has introduced 58 bills this Congress including:

Booker, the former Newark mayor and rising star first-term New Jersey senator, has sponsored 37 bills this Congress, including:

Trump’s likely picks

Corker, the second-term Tennessee senator and former mayor of Chattanooga who chairs the Senate Foreign Relations Committee, has introduced 20 bills this Congress that are perhaps the most non-ideological of any of VP contender for either part, including:

S. 2152, the Electrify Africa Act, was signed by President Obama and became law in February. It provides funding and initiatives with a goal of providing electricity to 50 million Africans who currently lack it.

S. 553, the End Modern Slavery Initiative Act, which would establish the titular “End Modern Slavery Initiative” and contribute funding accordingly.

S. 2201, the Global Gateways Trade Capacity Act, to expand U.S. trade with developing countries. Supporters argue that it could help such nations grow and could lower prices on goods and products here in the U.S., though opponents warn that free trade in developing countries can often perpetuate sweatshops and other horrific working conditions.

Ernst, the first-term Tea Party senator from the key swing state of Iowa, has introduced 20 bills this Congress including:

S. 1881, A bill to prohibit Federal funding of Planned Parenthood Federation of America, which would do exactly what its name implies. Planned Parenthood has come under attack by Republicans for supposedly selling body parts from fetuses and providing low-cost abortions which the pro-life Republican Party opposes, though Democrats say it’s a critical resource for women’s health.

S. 1411, the Presidential Allowance Modernization Act, which would limit taxpayer funds to former presidents under a formula that in practice would likely eliminate pension pay for most living former presidents. (It passed the House in January and the Senate just last week; no word yet on whether Obama will sign a bill limiting his own pay.)

S. 2582, the Midnight Rule Relief Act, which would prevent almost any federal agency from introducing or finalizing a rule or regulation between a presidential election and the subsequent inauguration about two and a half months later. (Presidents have sometimes implemented such rules that would be unpopular with the electorate during a lame duck session when they wouldn’t have to face the voters’ wrath.)

Sessions, the longtime conservative Alabama senator, was the first senator to endorse Trump in February, although eight months after Trump took the lead in national polls for the Republican nomination. He has introduced nine bills this Congress, and most of them that aren’t simple resolutions — like the one designating April 2015 as “National Congenital Diaphragmatic Hernia Awareness Month” — deal with immigration, arguably Trump’s signature issue:

Scott, the first-term Tea Party South Carolina senator and the only current African-American Republican senator, has introduced 15 bills this Congress including:

S. 1099, the Protecting Affordable Coverage for Employees Act or PACE Act, would change the Affordable Care Act (more commonly called Obamacare) to redefine as a “large employer” companies with more than 50 employees instead of the current 100 employees. Small group markets are required under current law to provide additional health insurance coverage that large group markets aren’t, so this bill would lessen Obamacare requirements for any business with 50–100 employees

S. 1897, the Safer Officers and Safer Citizens Act, which would give the Department of Justice grants to increase the use of body cameras for law enforcement officers, which have been shown to decrease reckless behavior on officers’ part such as police brutality.

S. 265, the Creating Hope and Opportunity for Individuals and Communities through Education Act or CHOICE Act, which would expand school vouchers and school choice programs. Proponents — mostly conservatives — say it allows students to not be victims of geography in cases where there local schools are underperforming. Opponents — mostly Democrats — argue it largely uses taxpayer money to subsidize students attending religious private schools which is a violation of the separation of church and state, plus that it is an alternative to improving the public schools which most students attend.
