Mike Pence's selection as Donald Trump running-mate is playing to mixed reviews, but voters don't figure to have much trouble deciphering where the "social issues warrior" stands on issues.

While viewed by many as controversial, the Indiana governor's stance on such hot-button issues as immigration, abortion, gun laws and gay rights have been well documented during his time in Congress.

Immigration

Much like Trump, Pence has long taken a hard-line stance on immigration, advocating for increased border control and expressing a preference for outlawing any path to citizenship for undocumented individuals.

Pence also once cosponsored a bill that would make English the country's official language and previously issued an order that prohibited Syrian refugees from entering the state of Indiana.

"Trump choosing Pence as his running mate is, again, only doubling down to be the most divisive campaign in American history," said Martin Garcia, director of campaigns for the Latino Victory Fund.

Abortion

Viewed as one of the most right-wing leaning members in all of Congress, Pence also signed what's considered to be one of the strictest abortion laws in the country and was even willing to shut the government down in the GOP's prolonged fight to defund Planned Parenthood.

Before being blocked by a federal judge, Pence signed into law a bill that outlawed abortion if a fetus had a "genetic abnormality" such as Down syndrome. The measure also stood to hold physicians legally liable if they knowingly performed such procedures.

Gun Control

Pence's "A" rating with the NRA is also well deserved, as he has regularly sided with the gun rights organization, including voting against an assault weapons ban.

Same Sex-Marriage

Pence has long been an opponent of gay marriage and once aided in passing one of the country's initial "religious freedom laws," which afforded businesses and individuals alike the rights to deny service to LGBT people over religious objections.

Healthcare

When it comes to healthcare and more specifically the implementation of Obamacare, Pence reportedly took the money offered by the government for the program, but quickly attached all sorts of conservative principles that pave the way for poor recipients to be dropped from the program if they failed to pay certain premiums.

Pence's so-called "Healthy Indiana Plan 2.0" also requires beneficiaries to have "skin in the game" in the form of paying into health savings accounts.
