Democratic National Chairman Howard Dean is coming to New Jersey on Friday to campaign for Paul Aronsohn, who is challenging GOP Congressman Scott Garrett in the fifth district. Dean may feel a bit queasy when he comes to the Garden State: when he visited in December 2003, he was the front runner for the 2004 Democratic presidential nomination. He came to accept the endorsement of Governor James E. McGreevey and much of the state’s Democratic establishment. But within a few weeks, his bid for the White House had come to a crashing halt. But Dean may have an affinity for Aronsohn, who was McGreevey’s press secretary — he once proclaimed January 27, 1997 as “Rotary Founder’s Day” when he was the Governor of Vermont.
