Indiana Gov. Mike Pence, a former congressman, is in many ways what Trump is not: a strong social conservative with deep ties to the party’s establishment. As such, there is a record of deep disagreements between the two names on the top of the Republican ticket this year. Here’s a quick look at Pence’s and Trump’s policy positions:

TRADE

Pence has been a longtime, aggressive advocate of trade deals like the North American Free Trade Agreement and the Trans Pacific Partnership. Trump wants to revoke NAFTA and do away with the Obama administration-negotiated TPP. He has made his opposition to trade agreements the centerpiece of his economic argument.

In 2014, Pence called for ratification of the TPP on Twitter: “Trade means jobs, but trade also means security. The time has come for all of us to urge the swift adoption of the Trans Pacific Partnership.”

IMMIGRATION

Pence came out against Trump’s proposed temporary ban on foreign Muslims entering the United States in November. He said on Twitter: “Calls to ban Muslims from entering the U.S. are offensive and unconstitutional.”

Pence also last month criticized Trump’s speculation that a federal judge born in Indiana was ruling against him in a lawsuit because of the judge’s Mexican ancestry. He called Trump’s statements “inappropriate.”

SOCIAL ISSUES

Trump has distanced himself from conservatives on social issues, saying Planned Parenthood “has done very good work” for some women and questioning Republican efforts to require transgendered people to use the bathrooms of their natural-born gender. Pence, in contrast, is a well-known social conservative who proposed defunding Planned Parenthood in 2007 and urged blocking the entire federal budget in 2011 in hopes of closing down the nonprofit organization.

TONE

Trump, famously, has turned presidential politics upside down, relishing personal jabs at his rivals and their families.

In 2000, Pence issued an agenda for the coming congressional year: “Campaigns should demonstrate the human decency of the candidate, recognizing that your First Amendment rights end at the tip of your opponent’s nose. Negative personal attacks have no place in public life and serve to erode public confidence in our basic institutions of government.”
