Geraldo: I Might Run for Senate Rivera says he's 'truly' considering a run in New Jersey By Newser Editors and Wire Services Posted Jan 31, 2013 5:35 PM CST 57 comments Comments Geraldo Rivera speaks on the "Fox & friends" television program in New York. (AP Photo/Richard Drew, file) (Newser) – None other than Geraldo Rivera says he's considering a run for US Senate in New Jersey. "Buckle your seat belts!" said Rivera as he announced on his radio show on WABC-AM in New York that he is "truly contemplating" a Senate bid. He said he has spoken to some people in the New Jersey GOP about a run, but he didn't say what they told him. "I figure at my age if I'm going to do it, I gotta do it," said Rivera, 69, who also hosts a weekend show on Fox News. Rivera got a mixed response when he asked his 30,000 Twitter followers how they feel about him challenging either Sen. Frank Lautenberg or Newark Mayor Cory Booker. At 89, Lautenberg is the oldest sitting US senator. The Democrat hasn't said whether he will seek re-election. Booker, also a Democrat, has announced he is exploring a run but hasn't made clear whether he would challenge Lautenberg in a primary, should he seek another term. No Republican has formally announced an interest in running.
