Answer by taking a quote from the following article:

Michael Richard Pence (born June 7, 1959) is an American politician and lawyer serving as the 48th and current Vice President of the United States, since January 20, 2017. He previously was the 50th Governor of Indiana from 2013 to 2017 and a member of the United States House of Representatives from 2001 to 2013. Born and raised in Columbus, Indiana, Pence graduated from Hanover College and earned a law degree from the Indiana University Robert H. McKinney School of Law before entering private practice. After losing two bids for a U.S. congressional seat in 1988 and 1990, he became a conservative radio and television talk show host from 1994 to 1999.

Michael Richard "Mike" Pence was born June 7, 1959, in Columbus, Indiana, one of six children of Nancy Jane (nee Cawley) and Edward Joseph Pence Jr. (1929-1988), who ran a group of gas stations. His father served in the U.S. Army during the Korean War and received the Bronze Star in 1953, which Pence displays in his office along with its commendation letter and a reception photograph. His family were Irish Catholic Democrats. Pence was named after his grandfather, Richard Michael Cawley, who emigrated from County Sligo, Ireland, to the United States through Ellis Island, following an aunt and his brother James, and became a bus driver in Chicago, Illinois. His maternal grandmother's parents were from Doonbeg, County Clare.  Pence graduated from Columbus North High School in 1977. He earned a BA degree in history from Hanover College in 1981, and a JD degree from the Indiana University's Robert H. McKinney School of Law in Indianapolis in 1986. While at Hanover, Pence joined the Phi Gamma Delta fraternity, where he became the chapter president. After graduating from Hanover, Pence was an admissions counselor at the college from 1981 to 1983.  In his childhood and early adulthood, Pence was a Roman Catholic and a Democrat. He volunteered for the Bartholomew County Democratic Party in 1976 and voted for Jimmy Carter in the 1980 presidential election, and has stated that he was originally inspired to get involved in politics by people such as John F. Kennedy and Martin Luther King Jr. While in college, Pence became an evangelical, born-again Christian, to the great disappointment of his mother. His political views also started shifting to the right during this time in his life, something which Pence attributes to the "common-sense conservatism of Ronald Reagan" that he began to identify with.  After graduating from law school in 1986, Pence was an attorney in private practice. He ran unsuccessfully for a congressional seat in 1988 and in 1990. In 1991, he became the president of the Indiana Policy Review Foundation, a self-described free-market think tank and a member of the State Policy Network.  Pence left the Indiana Policy Review Foundation in 1993, a year after beginning to host The Mike Pence Show, a talk radio program based in WRCR-FM in Rushville, Indiana. Pence called himself "Rush Limbaugh on decaf" since he considered himself politically conservative while not as outspoken as Limbaugh. The show was syndicated by Network Indiana and aired weekdays 9 a.m. to noon (ET) on 18 stations throughout the state, including WIBC in Indianapolis. From 1995 to 1999, Pence also hosted a weekend political talk show from Indianapolis.

Why did he lose both the '88 and '90 race?
