Bonini announced he would run for governor shortly after the 2014 elections. He stated that his campaign would focus on fixing the state’s “significant systemic and fundamental problems.” Although facing a significant obstacle as a Republican running statewide in the heavily Democratic state, Bonini said, “I am in it to win it. Delawareans deserve an election, not a coronation.”

In 2010, Bonini unsuccessfully ran for state treasurer, losing to Democrat Chip Flowers. Flowers received 51 percent of the vote to defeat Bonini by 6,121 votes.

Bonini was elected in 1994 to represent the 16th District in the Delaware Senate. The district covers part of southern and eastern Kent County along with a small portion of adjacent Sussex County. It includes the southern portions of Dover around the Dover Air Force Base and the towns of Frederica and Harrington.

Bonini received his B.A. from Wesley College in 1991. While in school, he worked for Bill Roth and the U.S. State Department in New Delhi, India. In 2001, he married Melissa Harrington, a biology professor at Delaware State University. They live together near Dover.
