(CNN) Democratic nominee Phil Murphy will win the New Jersey governor race, CNN projects.

Murphy's victory over Republican Lt. Gov. Kim Guadagno shifts control of the governor's seat to Democratic hands following eight years of Republican rule under the tenure of Gov. Chris Christie. It also means that should Sen. Bob Menendez leave office next year, he would be replaced by a Democrat, maintaining the current balance in the US Senate.

Christie, a once-popular Republican in the blue state of New Jersey, has seen his popularity decline sharply over the years, as the Bridgegate scandal and his embrace of President Donald Trump weighed on New Jersey voters. Quinnipiac University polls taken over the past several months peg Christie's approval rating regularly in the mid to low teens.

Guadagno has sought to distance herself from Christie's toxic image in the state, but as his lieutenant governor, she failed to sway voters, who Quinnipiac showed gave her low marks as well.

New Jersey holds its elections in off years, meaning the year after the nation elects its president, the voters of the Garden State must return to the polls to choose their governor. Over the past several cycles, these elections have delivered governors from the opposite party of the President.
