Rep. Tom Kean Jr. represents New Jersey's most competitive district this November " but nobody, even his GOP colleagues, can say where he's been for the past month. A scion of one of the state's most storied political dynasties, Kean's team says the two-term congressmember is facing unspecified health issues. The New Jersey Republican hasn't voted since March 5 and has missed almost 50 roll call votes. The other two Republicans in the New Jersey delegation, Reps. Chris Smith and Jeff Van Drew, said they have called and texted Kean out of concern for his health. But so far, neither said they have heard from him. Van Drew said it's been "radio silence."
