Background: Boyle, 57, of Bay Shore, is running for re-election on the Republican, Conservative, Independence and Reform party lines. Boyle was first elected to the senate in 2012 and served two stints in the Assembly, from 1994 to 2002 and from 2006 to 2012. An attorney, Boyle said he does limited work in the field currently. He earned a bachelor's degree in political science from the University of North Carolina, a master's degree in public administration from the University at Albany and a law degree from Albany Law School. He is married with two stepchildren.

Issues: Boyle cites his leadership on the issue of opioid addiction, including previously serving as chair of the senate's task force on heroin and opioid addiction, as among his proudest accomplishments while in office. Boyle, who is chair of the Commerce, Economic Development and Small Business committee, said he's been focused on passing "reform legislation to end corruption in Cuomo's economic development programs" and return oversight of the programs to the state controller's office. He said that in addition he wants to work on keeping millennials on Long Island by creating jobs through a more business-friendly climate and building more affordable housing. Boyle said he also wants to continue to work on animal welfare issues, including a proposed bill to end the sale of giraffe parts in the state.

Background: D'Amaro, 57, of North Babylon, is running on the Democratic, Working Families, Working Families and Women's Equality lines. D'Amaro served 12 years on the Suffolk County legislature until reaching his term limit in 2017. An attorney, D'Amaro took a leave from his law firm, Rivkin Radler, LLP in Uniondale, when he decided to run for the senate. He received a bachelor's degree in political science from Stony Brook University and earned a degree from St. John's Law School. He has two sons.

Issues: D'Amaro said he wants to focus on possible "workarounds" to the new federal tax laws that could preserve the deduction of state and local taxes on federal income tax returns. D'Amaro said he would also like to work on corruption in Albany, with one priority being passing a "sweeping" ethics reform, including limiting outside income for legislators, putting term limits on leadership positions, prohibiting the use of campaign funds for criminal defense costs and granting the state controller's office more oversight of state contracts. He said he would also like to work on campaign finance reform to "take the money out of politics." D'Amaro said he's also looking to enact "reasonable gun safety regulations" such as a "red-flag" bill to enable school officials to get a court order to prevent an individual from purchasing or possessing a gun if they are deemed at risk of doing harm to themselves or others.
