Newark Mayor Cory Booker (D) said Sunday that his immediate attention is focused on helping Democrats win in this year's slate of New Jersey elections more than it is on next year's Senate race.

"Right now we have one election in New Jersey, which is our state-wide gubernatorial and legislative elections," Booker said on CBS News' "Face The Nation." "As a Democrat in New Jersey, that’s where my focus is. Next year’s election for Senate will take care of itself, and again, I hope to be one of those people that the residents of New Jersey will consider giving that honor of fighting for them on a federal level."

Booker has actively moved toward a Senate bid, even as he has not said he is officially a candidate. Even before Sen. Frank Lautenberg (D) announced last week that he will retire, Booker had already filed paperwork for he race. He sought to downplay his own activities Sunday, drawing attention to supporting the Democratic nominee in the governor's race, which many in Booker's party had once hoped he'd enter.

"2014 is a long way off. Let’s focus on supporting the Democratic nominee for governor, and frankly, a lot of legislative races are up for grabs right now in New Jersey," Booker said.
