(NEW YORK) -- Voters in New Jersey will head to the polls on Tuesday to cast their votes in the state's primary election for U.S. Senate. Among those on the ballot to replace Democratic Sen. Frank Lautenberg -- who passed away on June 3 due to complications from viral pneumonia -- is Newark Mayor Cory Booker, who is widely expected to win the Democratic primary.
Booker faces competition from state assembly speaker Sheila Oliver and two Democratic House members, Rush Holt and Frank Pallone.
On the Republican side, businessman Steve Lonegan is expected to win his party's nomination.
New Jersey voters will then take another trip to the polls on Oct. 16 for the special Senate election, before heading yet again to the polls the following month when Gov. Chris Christie is up for re-election on Nov. 5.
