Former Vermont Gov. Howard Dean (D) continued to bolster his standing among the most liberal segment of the Democratic Caucus as he received the support of Rep. Jerrold Nadler (N.Y.) on Sunday.

Nadler told the New York Daily News that Dean was the only one of the nine Democratic presidential candidates “with the nerve to sock it to the president.”

Nadler, who represents a heavily Democratic district that takes in lower Manhattan, the west side and portions of Brooklyn, is among the most liberal-leaning Members. In 2002, Nadler was tied with seven others as the most liberal-voting, according to calculations done by National Journal magazine.

Dean has now picked up seven Congressional endorsements although he is the only major candidate not currently serving in Washington.

The former governor is currently on his “Sleepless Summer” tour, in which he will visit nine cities in three days. The tour began in Falls Church, Va., Saturday night and will conclude tomorrow in New York City. His campaign is hoping to raise $1 million on the trip.
