NEWARK -- Nine days after their first debate, the two leading Republican candidates running to succeed Chris Christie as New Jersey's governor will take part in their second and final state-sponsored primary debate.

Here's a look at how and when to watch Thursday night:

TIME: 8 p.m. The debate is an hour long.

WHERE: NJTV's studios in Newark.

WHAT CHANNEL: NJTV will carry the debates live.

HOW TO WATCH ONLINE: The event will be streamed live by NJTV and NJ Spotlight.

WHO WILL DEBATE: State Assemblyman Jack Ciattarelli and Lt. Gov. Kim Guadagno.

They are two of the five Republican candidates running in the June 6 primary for the party's nomination to succeed Christie, a term-limited Republican scheduled to leave office in January.

They were the only contenders to qualify for the debates, which are sponsored by the state Election Law Enforcement Commission, New Jersey's election watchdog agency. Candidates must either raise $430,000 or have that amount in their campaign coffers to be on stage.

WHO WON'T BE ON STAGE: Three Republicans did not qualify: Nutley Commissioner Steven Rogers, businessman Joseph Rullo, and engineer Hirsh Singh. Singh sued ELEC to participate in the debates, saying he raised enough money, but he lost his bid in court.

WHO IS THE MODERATOR: NJTV chief political correspondent Michael Aron will moderate the debate. NJTV correspondent David Cruz and NJ Spotlight CEO John Mooney will also ask questions.

WHAT HAPPENED LAST TIME: In their first debate, held last Tuesday at Stockton University, Ciattarelli and Guadagno agreed that cutting New Jersey's notoriously high property taxes is the top issue in the race -- but they disagreed on how.

Gudagno pitched her plan to slash taxes by capping the amount of homeowners pay in school taxes at 5 percent of their household income. Ciattarelli pitched his "five-point plan" that focuses on rejiggering the state's school funding formula to save money.

Both candidates also tried to distance themselves from Christie, whose approval ratings have been at historic lows of late.

WHAT THE POLLS SHOW: The most recent poll in the Republican race, released earlier this month by Quinnipiac University, shows Guadagno leading with 23 percent of the vote, followed by Ciattarelli with 12 percent, Rogers with 5, and Rullo with 3.

But the survey also found 51 percent of Republican voters have yet to decide whom they are supporting.
