Guadango served concurrently as the Garden State's lieutenant governor and secretary of state. She was first elected in 2009 as Gov. Chris Christie's running mate.

Creation of lieutenant governor's office

The position of lieutenant governor was created as the result of a constitutional amendment to the New Jersey State Constitution passed by the voters on November 8, 2005. In New Jersey, the governor and lieutenant governor are elected on a single ticket in the general election. Following the primary elections, gubernatorial candidates have 30 days to select a running mate. Guadagno was selected by Gov. Chris Christie to be his running mate for the 2009 campaign, the first in the state's history to include voting for a lieutenant governor. Following the election, Christie appointed Guadagno to the position of secretary of state as well, combining the duties of both offices.

June 2017 request for voter rolls

On June 29, 2017, the Presidential Advisory Commission on Election Integrity, which had been created by President Donald Trump on May 11, requested information on registered voters from all 50 states dating back to 2006. The states were given until July 14 to respond. Noting her ongoing participation in the 2017 gubernatorial election, Guadagno recused herself from responding to the request, referring the matter to the New Jersey Division of Elections.

In 2007, Guadagno became the first woman elected as sheriff in Monmouth County history.

Pension controversy

Guadagno reportedly made false statements in September 2008 that enabled a police official to improperly obtain $170,000 from a state pension fund, according to New Jersey Watchdog. Guadagno, Monmouth County Sheriff at the time, had hired Michael W. Donovan Jr., a retired investigator for the Monmouth County Prosecutor's Office, as her new chief, announcing in a memo to her staff that he would be replacing John Cerrato. Under state law, Donovan should have stopped receiving retirement benefits as a result of his employment and been re-enrolled in the Police and Firemen's Retirement System. However, Guadagno had placed him as Chief Warrant Officer, a position that is exempt from PFRS and the rules/regulations that apply to it. Those statements were deemed false since the position of Chief Warrant Officer had been eliminated by an order signed by Guadagno on Sept. 16, 2008 – the week before Donovan started.

? Guadagno endorsed Chris Christie for the Republican primary in the 2016 U.S. presidential election.
