The race between Murphy and Rubio has been heating up in the final two months of the campaign. It’s a seat that could be pivotal in determining which party controls the upper chamber next year.

Rubio goes into the race with higher name recognition after his unsuccessful run for his party’s nomination for president. A RealClearPolitics polling average has him ahead by 4.4 points.

Still, political observers in the state expect the race to tighten as it gets closer to November and believe the Senate race will hinge on voter turnout and what happens at the top of the ticket.
