One bit of circumstantial evidence that veteran State Senator Robert Littell will retire: two close political allies of the Littell family are already running for the State Assembly. Tewksbury Mayor Shaun Van Doren formally announced his bid over the weekend, and Sussex County Freeholder Glenn Vetrano has made it clear that he intends to become a candidate. It seems unlikey that Van Doren and Vetrano would both be in the race this early, unless they are planning to run on a slate that included Littell’s daughter, Assemblywoman Alison McHose, as the Senate candidate. Sussex GOP sources say that the Littell, Littell, 71-years-old and in poor health, is giving serious consideration to retirement, especially if it will help his daughter move up. Assemblyman Guy Gregg is set to formally enter the Senate primary in the next few weeks. Jim Logue, a Republican from Burlington County, has filed an ELEC complaint against Gregg, alleging that he is spending money on a Senate bid using his Assembly campaign account. A recent letter to Republican leaders was paid for by Guy Gregg for State Senate, according to the disclaimer, even though such a committee has not yet been filed. Gregg has used his Assembly committee to pay a Federal Election Commission fine connected to his failed 2002 U.S. Senate bid.
